I've done this many times on A and B bodies. I agree with several of the suggestions about doing the lower hinge only, jacking the door and the pilot hole.. BUT. Especially if you are doing this as a one man project, Try to avoid taking the fender off to eliminate risking chipped paint. plus realinging the fender can be a real pain. In any case a couple layors of masking tape on door and fender edges will help some. If you can, remove the splash shield in the fender well. Sometimes the bolts are rusted and you cant. If you can get it off, you will have access to the door hinge from there. First open the door and remove the 2 closest lower door bolts, the third you will get off thru the wheel well with the door closed. Drill your pilot hole from the interior, remove the interior hinge bolts and close the door. Go in the wheel well and remove the remaining bolts. When you reinstall repaired hinge, use a drill bit to locate the pilot hole. Lightly bolt the hinge to cowl and place 1 bolt in the door thru the hole in hinge, snug this one first, then the tighten hinge to cowl making sure you get the bit out.. Open door carefully and replace cowl bolts and door bolts. From there it is a matter of adjusting till you get a good fit.
