66 Dart driver's side mirror not same as 67 up?

So you're "adding" the remote style to your 67 cuda? The mirror appears same as our 67 remote.
Cables may be different lengths? Maybe mirror was on a b body originally?
You got hole on inside of door?

I have the hole on the inside of the door, so that car had a remote mirror stock. The previous owner installed some aftermarket mirrors and I want to go back to stock.
