63 Signet Drivers Mirror Replacement

The hole up front is for the mounting bolt. The small rear hole is for the rear mounting screw. I don't have any idea how the previous owner put a remote control mirror into that door, but there should be a larger hole between the other two to slip the cable into. If you have a gasket for the remote mirror, it will have the large hole in it which will tell you where to drill the door.

I agree with 66valiant528 (post 3) that a remote outside rearview mirror was not an option for 63 Valiants. However, one will fit once you drill the proper holes, in the proper places, and I have one on my 63 Valiant convertible. The driver's door is basically the same 63-66. One caveat: If you put the remote mirror where the non-remote mirror was, you won't get a full view out the mirror, as the vent wing rear post is in the way.
