I have a 1981 Z28 and am looking for a set of front inner fender wells. It's a Pro-Street car I'm making look more street. I often see 1970-1981 used parts listed as interchangeable, but when ordering new they split between 1970-77, and 1978-81. That is very confusing. Since it's a Pro-Street car and not a correct restoration I don't care if there are subtle differences. I just want to know if I can use 1970-77 inner fender wells with the 1981 without too much difficulty and what the differences are. Thanks in advance!
