1982 Door Adjustment

[barry1982]

Hi Guys,
Well, attempted to install the drivers door on my project 82 last night. Im using a good door off of a different truck. I installed the bolts insuring they were in the same location as originals (could tell by paint around washers). My new door is way out. Seems to be too close to back of cab , and "sagging" at rear bottom. I'm thinking I have to loosen/ adjust hinge mounts on cab to correct. (have also installed new pins/bushings) The top hinge as a bolt that comes from the inside. Can I loosen the nut on hinge, or is it spot welded?
