Without replacing the entire door hinge there are not a lot of options on repairing the rollers. I drilled the top of the roller off to find a worn stud.
I used a barracuda gas cap, stock filler tube, and exhaust tube for a better angle. The dorman filler gasket just needs a 2/5/16 hole drilled in the top of the tank. I melted the stock filler holes closed.
IF you cut a section off the back of the alternator backing, remove the protector for the terminal, and run no gasket just rtv you can get just enough room
