I own a 1974 U.S. spec GTS. When I got the car, the plastic Dodge Omni/Colt outside rear view mirrors that mount to the window glass with adhesive were installed on it. The driver's side mirror came apart last week when I shut the door. I plan to restore the car over the next several years maintaining the original exterior appearance. It appears that for cars originally sold through Lincoln-Mercury in the early 70's, outside rear view mirrors were installed by the dealer once they reached the United States, using stock Ford mirrors that were standard equipment on '67-'68 Mustangs and other Ford vehicles through 1973. I believe the Ford part number for these mirrors was C7AZ-17696-A. Good reproductions are commonly available from most vintage Mustang parts suppliers for about $55 each. These mirrors can also be ordered with convex glass on the passenger side to improve rearward vision. This design/shape of the mirror is symetric so they can be used on either driver or passenger side, although it appears they were commonly only installed on the driver's side on new Panteras. Can someone verify?
