1990 GMC Vandura/interchangeable parts

Introduce Yourself…

I am 71 and I just bought a “hippie van”. They spray painted the inside, horribly. It is a 1990 GMC Vandura 2500. I have access to a 1988 Chevy Vandura and am trying to find out if the body parts are interchangeable?
Anyone know where to find out this info.
Thank You

Do a search on “chevy van body parts”, I found several places that sell parts. When you go in and look at particular part they MAY have a lit of years that THAT part will fit on.

That’s where I’d start, good luck!
