The hinges and bolts are painted body color. They were adjusted to give a 3/16 inch gap to the rear and rocker before painting (the fenders were fitted to the door after paint).
I made a tool to remove the springs. I used a bracket from a 67 200 I6 alternator because of the welded in nut. There's a slot for the door stop that you will hve to make.
If you break off the roller stud, drill it out "carefully". There is a replacement in the rebuild kit. I use a hammer and drift pin to get the hinge pin out. There are brass bushings used as bearings.
If you opt for a new hinge, 64 1/2-65 have a squared off plate end, 66 hinges have a beveled end.
