Do GMC trucks use the same parts?

For all years we carry, the fenders and running boards are the same between Chevy and GMC. There are a few other parts that interchange as well. The hoods and grills are always different. So if you are looking for a 1950 GMC fender, our 1950 Chevy fender will work just fine. In some case, minor trimming may be needed to accomdate the GMC grill or trim peices. I have a 19xx Buick/Olds/Pontiac/Cord/etc – will the Chevy fiberglass parts interchange? As a rule, NO. There are a few exceptions that we have been made aware of through the years: • 1940 Olds – 1940 rear fenders and coupe deck lid work • 1940 Pontiac – 1940 coupe deck lid works • 1935 Pontiac Firechief 3 win & 5 win – 1936 Master deck lid works If you know of any more, please let us know!  more
