Special wrench helps
I just replaced mine moments ago. 94 Bonny but should be the same as yours. There are two 10mm nuts holding it on. Once you got the door panel off and all the wiring connectors disconnected. It helps to have the window mechanism plate loosened, but nothing needs to be disconnected other than the 10mm nuts holding the plate onto the door. Now it is a reach up into the door. The front nut of the mirror is easy. A 10mm socket and extension will do. The rear is tough. You can get a socket on it but glass from the window prevents an extension or universal from being used. I found a 10mm flare nut wrench that the head swivels to do the trick. I bought it at Auto Zone. A 10mm box wrench doesn't have the right angle to work.
Some postscrpts; I did it with the window UP. I doubt that it can be done with the window down. I also removed the front window slide. I think this was attached to the window mechanism. Be careful that it is aligned on the leading edge of the window when putting things back together. The leading edge glass is what makes access to that rear stud of the mirror difficult.

Reason: additional thoughts.
