I am restoring a 1968 Corvette Bronze Camaro - 327/210, powerglide, factory AC, etc...i have located a correct set of 14x6 rally wheels but want to know which are the correct center caps. I have looked at parts suppliers and Camaro websites only to get more confused! My car is not a disc brake car. Flat caps or tall caps, which would have been installed from the factory? Thanks, Lance in TX.
