2nd generation cuda question

I had an error. The 69, not 68, right mirror was code G-31


The angle of the mirror frame is slightly different for passenger side. This is the only style they came in IF the passenger side mirror was factory.

Is there really a diff. between the right and left mirrors ? thinking about an adjustable one for the drivers side, and trying to use the original for the pass. side. any comments? I ain`t worried about restoration either, want it to look stock, but run like ----gang busters!
