Hoooowwwwdy!

Yes, the all thread or stud works for the drivers side, but the passanger side mirror has a hole that goes all the way through into the area where the mirror is and then the same hole at the back just like the driver side mirror. I did get a gasket off a junker and the holes in the passenger door are already there. She came off the assembly line with both mirrors. Thanks for the info! :)
