Am I missing something here? My drivers side mirror popped off and broke in my driveway. I went to the Ford Dealership and paid like $10.00 for a new one and it clicks on, no epoxy or other stickem's. I had to hold the back and give it a good knock but it clicked in and haven't had a problem since. Maybe's it's because mine are power mirrors, they are different.........I don't know.
