The whole cab is really just a big “box”, right? So, when I installed all new roof and body wood I had to keep all the corners pretty loose until both of those inner moldings would snuggle back in by “rocking” the whole windshield frame and the door openings back and forth. Then the header across the front and the door frames could be tightened up in their respective brackets, but not all the way until the door opening was right. Also had the windshield frame slid out of its hinge at the time and slid it back in last. Hard to describe the process any better, sorry, I literally I just shoved the roof around from side to side and front to back while squeezing those garnish molding panels in with clamps. Definitely no shame in some light filing to fit though, especially considering the amount of tweaking the cabs went through over the years of use. Stock truck was twisted quite a bit and really rough, but eventually the doors and windshield frame opened and closed fine after a lot of adjustments to the shims under the whole cab. The channeled hot rod cab is even rougher so it might give me even more grief… Good luck, its tricky to get everything to all line up at the same time and the shims between the frame and cab take a lot of trial and error… Chris, in Boulder
