Rick - fit and finish were important - within the limitations of the design, the wrap around windshield years were particularly tough for fitting, if a door didn't fit the first truck it was tried on a 2nd, maybe a 3rd and even a 4th, and then it went into the service parts pile, with the real fiddling left to the bodyman when it was used for collision repair - and if things weren't quite 100%, the dealers had prep crews that dealt with the final touchups to make things acceptable for a work truck .... trucks didn't get the picky treatment afforded luxury cars
