Tell ya what I did. Takes a few more people but easier than the hassle of adjusting in the end. I first took a die grinder with a small cutting disc and cut the swedged (lower) ends of the hinge pins off. With the door open, and several people holding the door steady, I tapped the pins up and out of the hinges with a slightly smaller OD punch. Lower first, and then the top. (Tape off the door and fender edges in case the door slips).
Once the pins are out remove the door carefully. Watch the flying holding spring (I tied it up with wire before-hand. Once removed, the hinge/halfs are out in the open. Mark or drill small index holes through the hinges into the body or doors. I just scribbed mine. Once rebuilt, the halves can be reinstalled in the same location making adjustment allittle easier.
As for rebuilding the hinges, I didn't go with the replacement bushing and pin route. I went to our local hardware store and found flanged bronze bushings that were larger. 3/8" ID and 1/2" OD. Think the flange is slightly larger than 5/8" in diameter, had to file some of the thickness off. I drilled the outer half (hinge) out to 3/8" and the inner half to 1/2". I then used a 3/8" X 4 1/4" long, I think (no threads in the bushings) grade 8 bolt as the pin with a nylon lock nut to hold it all together.
Had to do it this way as my pins had worn the hinge out so far the original bushings won't work anymore. These are much stronger and will last forever. Reassemble with the same amount of help with the bolts going in from the bottom. Adjust if necessary.
I didn't reuse the holding springs but theres a tool out there to reinstall them once all is adjusted.
Wish I had some pictures.......sorry,
