My '82 D350 crew cab's cab is beat to hell and gone, and I stumbled across one for sale from an '86 that has had all its bodywork and paint completed and is disassembled down to its welded sheet metal stamping, with the rear doors included. It was even painted the color that I want to paint mine, and since none of the rest of my sheet metal is painted yet, painting my parts to match this cab seems practical.
Anyway, what I'm not certain of is if there are any differences that will need to be accounted for. I wouldn't expect so, but Dodge did change rear windows and the opening sizes a few times in the years they built this basic design.
Any insight would be much appreciated.
