Original style radiator cap.
This question I posted in cooling but no luck there but this could also be an originality question also. I just need to know what is the original style radiator cap that came on our cars. Mines an 89 iroc with a 350 tpi. I have found 3 different styles of the original ac delco part # of rc27 or gm # 10409635. The 3 that come up are a round silver cap, a round cap that has turning ears and a black label and a black plastic cap. For you guys with unmolested cars, let me know if you still have the original cap and which style it is. Thanks.

Re: Original style radiator cap.
I got two nice used originals for sale if you need one (or both) ...
These are the original from the factory correct caps.
