Stingr69,Thank you. So you are saying that rear hole should not be there, it is a countersunk hole that goes into the reinforcement like the 2 forward of the large hole.
Problem is I can't find a picture of a door with correct holes, I don't have a mirror bracket, and it will be painted soon.
Do you think this car could have had a remote mirror? Does anyone have a picture of original mirror holes? Thanks. George.
