gentlemen,
Anyone have luck finding an aftermarket cap to fit the coolant overflow tank for 1980 C3, on AMAZON?
Why is this so difficult….

This is what I found after a quick google search.



If you’re willing to use a website that doesn’t make the 4th richest man in the world richer many other vendors sell caps that look exactly like the factory piece.

The one in Piersonpie's link is the cap originally used on 84 and newer Corvettes, but it will work on 77-82's also and was sold as a 77-82 service replacement cap by Chevrolet. The one in SEVENT6's link is the correct cap for 77-82 Corvette's.
