I can see if I've still got a list of PN's somewhere. I know the indicators were a real pain in the ass to order because you have to order the black housing, indicator lens, and bulb separately. They weren't all stocked at the same company back in the day so it took multiple orders from a few different places to get all the right pieces. And they are stupid expensive for what they are. 5 years ago it was like 300 bucks for a set, who knows what they are now. They do also sell the indicators as momentary push button or push on/ push off switches as well, but unless you are planning on actually wiring them up to something to function you are better off just getting the indicators only. The cost for the switches was like 30 bucks a piece plus the cost of the lens.

The gold heatsinks are made of aluminum and finished with gold chem film. It's a type of chromate conversion coating used to protect the aluminum from oxidation / corrosion. It's a similar process to how zinc plated steel parts are finished to look yellow after zinc plating. It's tough to find places these days that will still provide gold chem film coatings because it typically requires hexavalent chromium. Most places now only provide trivalent chrome conversion coatings because of industry standards and toxicity of the hex chromium. Some places that offer trivalent conversion coatings will add a yellow dye to simulate hex chrome, but it doesn't look exactly the same.

The gold finish on the heatsinks was definitely original. There are other markings and PN's inked onto the heatsinks that would have been covered up had they been painted over or refinished. The production team who built the car were actually really good about preserving part numbers on the parts. I'm not sure if it was intentional or not but it adds some authenticity to each prop that makes it seem a little bit more real.
Well that is some great information on the heat sincs. Thank you so much! I'll need to start looking at my options for that.

Right now I have been looking for the rectangular and circular red / white / yellow indicators, but I was going to start looking for the rockers next, and would love to know about the green toggles if I could. I have heard about how expensive they are, and that they needed to be ordered as separate pieces, but I didn't hear that they were not all from the manufacture, I bet that is part of the reason I was having a hard time finding just the right model. I found several similar models, but none of them were quite the right shape. At this point I would like to get the actual switches, but your idea of just getting indicators is a good one.

Thanks again!
