Ther's nothing to install. Everything is in place and has been working up until recently. Nothing has been taken apart, the rod has not been removed. It's all as I left it after initial restoration a few years ago. It's just that it stopped returning the headlight covers to the closed position after turning off the lights. I really don't think that "centering" the motor is the problem here. It's an electrical problem, not a mechanical mechanical problem. Everything works perfectly when I bypass the existing electrical circuits and power the motor directly with 12 volts. The doors open and the doors close perfectly.
