I think they are the same but different years for those wheels have a different size/shape hole for the valve stem. the camaro's used them from 70-81 so if you want "correct" for a 72 you need to make sure it has the right valve stem hole. Other than that i think they were the same for camaro and chevelle but im no expert either. the only reason i know about the different holes is because i sold a set recently and got schooled by a few people.
