Has anybody ever taken the doors off? My driver's door has sagged so the swage line is not aligned with the one in the rear panel.
Actually the door may not have dropped, unless you can see that the door shell is damaged where the hinges mount. The problem is that the hinges were welded to the metal chassis and on the drivers side they were slightly out of line right from the start! Take a good look at many of the press release photos and you will see the drivers side didn't line up even right at the beginning! The way Matra got around the problem was to pack out the lower hinge mount to lift the door! Mine (a 1982 car) had a number of the same packing shims fitted as used elsewhere on the car (the boot locks for instance) to bring the door and swage line level.
I would also like to paint the door and and hinge assembly to give it a factory fresh look. It looks easy enough to knock the roll pins out but the door skin will be in the way of the front lower one because it curves under the pin. I was wondering whether there is a way of removing the hinges from the inside of the door perhaps?
You need to knock the lower pin out, upwards. I replaced my pins some years ago and did it that way.
As 'Speed Pete' says, I would not attempt to release the hinges from the doors with the doors still on, after all this time, unless you find the screws turn easily. Better to remove the pins, and then work on the door hinge mounts with the door off.
Those spacers are 'E' shaped so you only have to slacken the screws and you can then slide them into place, past the screws, before tightening them again.
Once you have aligned the door, don't forget to lift the anchor pin where the door catch locks!
