Power Mirror Question

I have a 90 GS 2-dr, which I am missing my dr. side power mirror. I have only been able to find another power mirror from a 90 4-door, and it looks the same, but the wrecker says that 2-door and 4-door cars use different mirrors.

Does anybody know if this is true? Would they mount differently, be a different shape, or what exactly is the difference? All I need right now is something that will fit so I can get my car through a safety inspection to get it licensed, then if I find one later I can always switch. Thanks for the help,

The windshield is at a different angle, so I know the plastic does not fit right, and I think one of the bolts might be in a different spot.
