I’ve seen enough restored classics to know that sometimes, what you think is right just isn’t.
Take the finish on those classic Olds parts. Everyone’s chasing that factory-fresh look, but the devil’s in the details. Specifically, when it comes to whether 1960 Oldsmobile hood hinges cad plated, the answer isn’t as simple as a quick Google search.
I’ve spent more time than I care to admit sorting through replacement parts, trying to get that perfect under-hood shine. Let’s cut through the noise and talk about what’s actually going on with those hinges.
The Truth About Original Finishes: Cadmium Plating and Its Era
Back in the day, especially in the late 50s and early 60s, cadmium plating was the go-to for a lot of automotive brightwork. Why? Because it offered fantastic corrosion resistance, especially in marine environments, and it had a distinctive, often slightly bluish-grey or silvery sheen. It was durable, relatively inexpensive for the protection it offered, and automakers loved it for parts that needed to withstand the elements. This was especially true for fasteners and structural components like hinges that weren’t necessarily meant to be flashy showpieces but needed to survive decades of use and exposure.
So, when you’re asking if 1960 Oldsmobile hood hinges cad plated, the historical record points towards ‘yes’. Many original components from that era, especially those not intended for high-heat areas or direct external exposure where chrome might be used, would have received a cadmium plating. Think about it: the hood hinges are exposed to rain, road spray, and general atmospheric conditions. They weren’t painted body color, and they weren’t typically chromed like bumpers or grille inserts. Cadmium filled that niche perfectly for functional corrosion protection with a decent appearance.
However, here’s where things get murky for restorers. Cadmium plating has fallen out of favor due to environmental and health concerns.
It’s a toxic heavy metal, and its use is now heavily restricted or banned in many places. This means finding new parts that are cadmium plated is nearly impossible, and even having old parts re-plated often involves specialized, environmentally conscious shops that can handle the process legally and safely. The original finish, while desirable for absolute authenticity, is becoming a unicorn. Many reproductions will opt for zinc plating, or even dichromate conversion coatings on steel, to mimic the look and offer some corrosion resistance without the cadmium headache.
This is a important distinction when you’re sourcing parts for a show-quality restoration versus just getting a driver back on the road.
My own experience with a ’65 Riviera was a prime example. I was chasing factory-perfect, and the hinges on the original car, while pitted and worn, had that unmistakable dull, slightly blue-grey hue.
I spent months trying to find NOS (New Old Stock) hinges, but they were either astronomically expensive or already past their prime. The aftermarket options?
They were mostly zinc-plated, looking too bright and uniform. I ended up sending my original, heavily corroded hinges to a specialized plater who could do cadmium, but it cost me an arm and a leg and took forever. Was it worth it for a car that wasn’t going to be trailered to Pebble Beach?
Probably not. But for that specific goal, it was the only way. (See Also: A Box Without Hinges Key )
What to Look for: Identifying Original vs. Reproduction Hinges
Figuring out if you’ve got original 1960 Oldsmobile hood hinges cad plated, or if you’re holding a reproduction, can be tricky. The finish is the biggest clue, but it’s not always obvious, especially if the part has been cleaned, painted over, or heavily corroded. Original cadmium plating often has a dull, matte finish, sometimes with a slight yellowish or bluish tint, especially as it ages. It’s not as bright or shiny as chrome or even fresh zinc plating. If you see a part that looks excessively bright and uniform, almost mirror-like, it’s probably not original cadmium. It could be a modern zinc plating, clear coating over bare steel, or even a powder coat mimicking a metallic finish.
The weight and feel of the part can also be a subtle indicator. Original steel stampings from that era were often made from thicker gauge metal than some modern reproductions, which might feel lighter or less substantial. However, this is highly subjective and depends on the quality of the reproduction. Look for any original part numbers or GM markings. These are usually stamped directly into the metal. While reproductions might try to replicate these, there can be subtle differences in font, size, or placement that an experienced eye can spot. Sometimes, the edges of these stamps on original parts are a bit softer due to age and wear, whereas reproductions can have very sharp, crisp markings.
Another thing to consider is the engineering. Were there any design tweaks or improvements made over the years? While 1960 Oldsmobile hood hinges cad plated is the question, the specific design of the hinge mechanism itself might have subtle differences between original GM parts and aftermarket replacements. For instance, look at the pivot points, the spring attachment points, and the overall shape. Sometimes, manufacturers will simplify designs for cost-effectiveness in reproductions, or they might update them to use modern hardware. Pay attention to the way the parts fit together and operate. Do they feel smooth and precise, or a bit clunky?
I remember buying a set of what I thought were NOS hinges for a different project. They looked the part, had what seemed like GM markings, but when I went to install them, the action was stiff, and one of the mounting holes didn’t quite line up. Turns out, they were decent reproductions, but not perfect. The original cadmium plating had long since deteriorated, and they’d been clear-coated over steel.
It looked convincing in the box, but in actual fitment and operation, the difference was clear. It taught me to always double-check markings, ask sellers about the origin, and if possible, compare them side-by-side with known originals. For 1960 Oldsmobile hood hinges cad plated, the original finish is key, but so is the overall construction and feel.
Common Mistakes When Replacing or Restoring Hinges
One of the biggest blunders people make is assuming all ‘bright’ finishes are created equal. They see a shiny silver part and think, ‘Great, that’ll look good!’ But that bright, almost mirror-like finish you often see on reproduction hinges is rarely, if ever, cadmium. It’s usually bright zinc plating, which offers good corrosion resistance but has a different aesthetic. For a concourse-level restoration where you’re trying to nail the factory look, this can be a deal-breaker. I’ve seen guys spend a fortune to get original-style cadmium plating done, only to have judges dock them points because the shade of silver was slightly off, or they used a modern zinc that was too bright.
Another mistake is not considering the hardware. If you’re replacing your hood hinges, you’ll likely need new bolts and washers to attach them. Original hardware was also often cadmium plated. If you slap on shiny, new, zinc-plated bolts with your restored or reproduction hinges, you’ve just introduced a visual inconsistency. It’s the little details like this that can make or break the authenticity of a restoration. It means sourcing correct hardware, which can be just as challenging as finding the hinges themselves. I once spent a week tracking down the correct, cadmium-plated bolts for a specific application because the standard ones just looked ‘wrong’ next to the original-style hinges.
People also tend to underestimate the amount of work involved in cleaning and prepping original hinges. If you’re going the route of trying to preserve or restore original hinges, you can’t just grab a wire brush and go to town. Harsh brushing can remove the remaining plating or damage the underlying metal. Specialized cleaning solutions and gentle methods are often required. And if the hinges are seized or worn, rebuilding them might involve sourcing bushings or pins, which aren’t always readily available for specific models. It’s a job that requires patience and the right tools. I’ve seen perfectly good original hinges get ruined by someone trying to force them open or clean them too aggressively. It’s a delicate process.
Lastly, there’s the ‘good enough’ mentality versus aiming for true authenticity. For a driver car, a good quality zinc-plated reproduction hinge might be perfectly acceptable and much more budget-friendly. But if you’re aiming for a show car or a historically accurate restoration, you need to be aware of the original finishes. The question ‘are 1960 Oldsmobile hood hinges cad plated?’ isn’t just about historical fact; it’s about understanding what that means for the visual and functional authenticity of your project. Don’t settle for ‘close enough’ if your goal is accuracy; do your homework on original finishes and hardware.
People Also Ask:
Were Oldsmobile Hood Hinges Always Cadmium Plated?
Not necessarily. While cadmium plating was very common for many functional metal parts on cars in the 1950s and 60s, including hood hinges, it wasn’t universal. Some components might have received other finishes depending on their specific application, heat exposure, or the particular manufacturing processes used by GM at the time. However, for parts like hood hinges that needed solid corrosion resistance without being a high-visibility trim piece, cadmium was a frequent choice.
Can I Still Get My 1960 Oldsmobile Hood Hinges Cadmium Plated?
Yes, it is possible, but it requires finding a specialized plating shop that handles cadmium plating legally and environmentally responsibly. Due to environmental regulations, many standard plating shops no longer offer cadmium services. It’s a more expensive and time-consuming process than common zinc plating, and you need to make sure the shop is reputable and experienced with automotive parts.

What’s a Good Alternative If Original Cadmium Plating Isn’t Feasible?
The most common alternative is zinc plating, often with a clear or yellow dichromate conversion coating to mimic the look of older finishes. While not identical to cadmium, good quality zinc plating offers excellent corrosion resistance and can be made to look reasonably period-correct. Some restorers also opt for durable powder coating in a metallic grey or silver finish, though this is less common for hinges and more for structural components that aren’t as visually important.
The Role of Zinc Plating and Modern Alternatives
Since we’ve touched on it, let’s dig into zinc plating a bit more. Zinc is the workhorse of modern plating for automotive restoration parts. It’s far more environmentally friendly than cadmium, significantly cheaper, and readily available. When you buy reproduction hinges today, they are almost certainly going to be zinc-plated. The appearance can vary. Bright zinc plating gives a very shiny, almost chrome-like silver finish. This is often too flashy for a period-correct look.
Then there’s zinc with a chromate conversion coating. Yellow chromate (often called ‘chromate’ or ‘yellow zinc’) gives a distinct golden or brassy hue, which is definitely not what original cadmium looked like. However, clear or blue/silver chromate can get you closer to a silvery appearance. The challenge is that the exact shade and tone can vary greatly between platers, and it can also change over time as it ages. Some clear zinc finishes can look quite good and pass muster for many restorations, especially if they aren’t aiming for absolute factory perfection.
Another option gaining traction is using specialized coatings that mimic the look of original finishes without being actual plating. These can include certain types of primers with metallic flakes, or even some of the more advanced paints that offer a durable, corrosion-resistant finish with a specific matte or semi-gloss metallic look. For example, some people have had success using high-quality industrial primers that have a grey, metallic appearance. These might not offer the exact same level of long-term corrosion protection as a proper plating, but they can achieve a visually convincing result for less money and effort.
I tried a set of zinc-plated hinges with a clear chromate finish on my ’68 Firebird project. They looked decent enough from a few feet away, and the price was right. However, up close, they were just a bit too clean, too uniform.
The original hinges on that car, even after decades, had a certain character, a subtle variation in the finish that these new ones lacked. I ended up going back to a set of salvaged original hinges that I had professionally stripped and then had re-plated in a matte zinc finish with a very light, almost invisible clear coat. It cost more, but the look was far more authentic. It’s a trade-off between cost, effort, and how important that original cadmium finish is to your specific project.
For 1960 Oldsmobile hood hinges cad plated, understanding the nuances of modern alternatives is key to making an informed decision.
Rebuilding and Refurbishing Original Hinges: A Deep Dive
So, you’ve managed to find a set of original 1960 Oldsmobile hood hinges, and they’re rough. Pitted, maybe a bit stiff, but undeniably original. Can you bring them back to life? Absolutely, but it’s not for the faint of heart, and it requires a different approach than just slapping on new parts. The first step is careful disassembly. These hinges are often riveted or pressed together. You’ll need to carefully drill out rivets or use a press to separate the components. Take photos as you go; trust me, you’ll thank yourself later when you’re putting them back together.
Once disassembled, the real work begins: cleaning and rust removal. This is where you need to be gentle. Aggressive wire brushing can remove the remaining plating and damage the metal. Start with a less abrasive method, like a good metal cleaner and a Scotch-Brite pad. For heavier rust, you might consider an electrolysis tank or a chemical rust remover. Electrolysis is fantastic because it removes rust without removing good metal. You’ll need a sacrificial anode, a power source (like a battery charger), and a solution of washing soda and water. It takes time, but the results are amazing.
After rust removal, you’ll need to address any wear in the pivot points. If the hinge arms are worn where they rub against each other or the pivot pin is worn, you’ll have slop. Sometimes, you can build up worn areas with a MIG welder and then grind them back to size. More often, you might need to replace worn bushings or pins if they are available for your specific model, or even have custom pins fabricated. The goal is to get a smooth, slop-free action. I had to do this on a set of hinges for a ’57 Chevy; the pivot pins were practically needle-thin from wear. Machining new pins was the only way to get them tight again.
The finishing touches are important. If you’re aiming for originality and your original hinges were cadmium plated, you have a few options. As mentioned, finding a cadmium plater is one. (See Also: Are Hinges Wheeels )
If that’s not feasible, you might opt for a high-quality zinc plating with a matte or satin finish. Some restorers also choose to paint them a satin black or dark grey, especially if the original cadmium was heavily deteriorated and the goal is a clean, functional look rather than concours authenticity. Just be sure to use a paint formulated for metal, like a durable enamel or a specialized chassis paint, which will hold up to the elements.
Whatever you choose, the key is meticulous preparation and understanding the desired end result.

The Faq: Getting Your Questions About Oldsmobile Hinges Answered
What Was the Primary Reason for Using Cadmium Plating on Car Parts in the 1960s?
The primary reason was its exceptional corrosion resistance. Cadmium plating provided a sacrificial barrier that protected the underlying steel from rust and degradation, especially in harsh environmental conditions like coastal areas or regions with heavy road salt use. It offered a durable, albeit sometimes aesthetically inconsistent, finish that extended the life of important components.
Are Modern Zinc-Plated Hinges a Bad Choice for a 1960 Oldsmobile Restoration?
Not necessarily a ‘bad’ choice, but a choice with trade-offs. Modern zinc plating offers good corrosion protection and is significantly more affordable and accessible than original cadmium. However, the finish is typically brighter and more uniform, which might not meet the standards for a high-level, concours restoration where historical accuracy is most important. For a driver car or a more budget-conscious project, they are often a very practical and acceptable solution.
How Can I Tell If My Current Hood Hinges Have Original Cadmium Plating?
Original cadmium plating often has a dull, matte finish with a slightly bluish or grayish tint, sometimes with a subtle yellowish cast as it ages. It’s not as bright or reflective as chrome or fresh zinc. If your hinges are heavily pitted or painted, it can be hard to tell. However, if you see a very bright, uniform silver finish, it’s unlikely to be original cadmium. Examining areas that may have been protected, like inside a bolt hole, might reveal more of the original finish’s character.
Is It Safe to Handle Old Cadmium-Plated Parts?
Cadmium is a toxic heavy metal, so caution is advised. While the plating itself is generally stable and safe when intact, processes that disturb it, such as sanding, grinding, or aggressive cleaning, can release cadmium dust into the air. It’s best to wear appropriate personal protective equipment, like gloves and a respirator, when working with old cadmium-plated parts, especially if you’re going to be disturbing the surface. Proper ventilation is also important.
What’s the Difference in Appearance Between Cadmium and Zinc Plating?
Cadmium plating typically has a duller, more matte finish with a slightly bluish-gray or yellowish hue, especially as it ages. It’s less reflective than bright zinc. Zinc plating, especially bright zinc, is much shinier and more reflective, often appearing as a bright, uniform silver. Clear or yellow chromate conversion coatings on zinc can alter its appearance, but it still generally looks different from aged cadmium.
Final Verdict
So, to nail down the question: are 1960 Oldsmobile hood hinges cad plated? The short answer is, most likely, yes, they were originally. That distinctive, corrosion-resistant finish was standard for many functional parts of that era.
But here’s the blunt truth: chasing that exact original finish today is a significant undertaking. New parts are rarely cadmium plated due to environmental regulations, and restoring original hinges requires specialized knowledge, tools, and often, a hefty budget. For most projects, especially driver cars, a good quality zinc-plated reproduction or a carefully refurbished original with a modern finish is the more practical route.
Before you buy anything, or start tearing into your existing parts, figure out what your end goal truly is. Are you aiming for a factory-perfect show car, or a great-looking classic that’s fun to drive? Your answer will guide you to the right choice for those all-important hood hinges.
