Re: Adding a passenger side mirror, help please!
The right side mirror doors had a reinforcement plate that the mirror screwed to welded to the inside of the door. I can get you some rough measurements off a door I have in storge if you want. there will be three holes, two screw holes and the third larger center hole for the control wires and knob to feed through. I would put a plate of some kind under the mirror for strength, a nut and bolt isn't going to be very strong.
