1963 Dart outside mirror options

I am curious as to what different manual mirrors were offered on the 1963 Dart? I amin the process of putting mine back together after painting it and realized my new twin post mirror I ordered won't fit the holes in the door. They are the original holes as the car was original paint when I purchased it. Unfortunately, the original mirror was missing when I got it so I just ordered the twin post as I thought that was original.

I read somewhere on here that there was different chrysler mirrors offered in 63 for these cars. I would like to replace it with the proper one if possible to eliminate having to deal with the extra hole in the door. Wouldn't have been an issue if I spotted it before paint, but too late for that now.

Any help would be appreciated.
