Does anyone have any advice for the following? So I am starting on the body work on my 72 and I noticed that the passenger door has a bit of a gap towards the rear of the cab, I measured both doors and there is about 3/16 difference between the drivers and passenger's side, it looks like there were a few shims added to the passenger's side. The gaps along the front all look pretty normal, and I can find no wrinkles in the cab anywhere to tell damage, there is a patch panel welded to the drivers floor board towards the front center. I am going to be replacing the front of both sides of the cab floorboards as it has the normal rot and also the inner and outer rocker panels, is there a fix for the gap issue that I should try since I will have the floor cut up?
