In an attempt to begin to add build help information to the forum I wanted to post how I installed my door mirrors. After trying to get a good position by setting the studs against the door I asked Kempo about his. He removed the studs to assist with the fitting. Initially I removed my studs; bus discovered that the large harness was still in the way. So I decided to try this:
After measuring 2 1/4" as per the manual I removed the two aft studs from the mirror housing. I then placed the mirror's rubber gasket in position using the passenger side for reference. I then drilled the forward 1/4" hole and a 3/4" hole for the mirror's harness. I then placed the mirror on the door and hand tightened the nut so that I could rotate the mirror about that stud, but it would not move on it's on. Then I sat in the GTM to ensure the mirror would be functional. I then carefully slid some tape between the mirror and the rubber gasket to hold it in place and rechecked its functionality. I then removed the mirror, drilled the two aft holes, replaced the two studs and installed the mirror.
