I agree with Dave. This truck happens to be one of our specialties. Maybe I should say was. Anyway I like to brace the jamb with the door on so I can use it for aligning the rocker. I start with the inner and outer rocker first. Once the rocker is tacked in good, I remove the door and replace the pan. Do this on both sides before doing any more welding. Re install the doors and jack the cab off of the cab mounts and replace one side at a time. Your cab should remain as square as posible. Last weld all areas throughly( continuous weld are not necessary).
dang wish i found this advice before I replaced cabcorners and rockers on my 72, but it didn't turn out to bad, the space between my rockers and the bottom of the door isn't too bad as long as you dont get down on your knees and look at it
