I fit the doors today...it went amazingly quickly and easily! (spider and front clip also in position) This is what I did:
1. For easy adjustment of the hinges during the fitting process, I created 2 plates for each hinge with holes drilled and tapped to accept my 1/4 inch bolts, which I put on the outside of the hinge so that I could easily loosen and tighten the bolts from inside of the car. I then drilled 4 holes in the frame aligned around each corner of the hinge, tapped, and inserted a #10x20 socket screw at each hinge corner. I could now easily move the hinge in and out from the frame by twisting the socket screws and adjusting the bolts.
2. I mounted the hinge loosely.
3. I installed the weatherstripping.
4. I placed the door in the proper position taking into consideration the position of the spider, front clip, and rockers. Yes, my tires do fit and turn in the wheel well.
5. I adjusted the hinge to fit the door by moving it in/out with the socket screws and up/down and front/back with the bolts (all from the inside) so that the hinge fit the door that was already positioned where I wanted it and tightened it all down. I ended up with a slight forward tilt to the hinge so that the door does not sag when opened.
6. I then removed the door from the hinge (I use a 10" bolt). measured the spacing required for between the frame and the hinge and created aluminum spacing plates. I drilled two holes to permanently affix the hinge in place. I then removed the socket screws and plates, installed the spacers and installed the hinge.
7. I attached the door to the hinge and did any fine tuning with the adjustable plates on the door.
8. I have a nice fitting opening/closing door!
