I know the drivetrain is interchangable, but I just found what I think is a dggm fleetwood in a yard, Will the exterior handles bolt up on a Caprice? Also would we be able to swap interior parts like the seats? Maybe door panels? I noticed the controls on the driver seat are identical to the ones in my RMW, and I'm trying to find some grey leather for my Caprice wagon, and I know the rear seat will take some mods to fit in a wagon out of a sedan. Any input fellas?
