QUESTION: The car is a two door coupe.

Answer
Pry at the top of the triangular cover inside the door with a flat screwdriver there will be 2 8mm nuts to remove as well as 1 forward of the window frame under a black plastic cap about 1/2" diam. Undo the plug and remove what is left of the old mirror installation is a matter of reversing the process. Should take about 10 min.
