Installing driver side mirror 74 corvette

by Chris

Hello,

I am trying to install a driver side mirror on my 74 corvette to replace a non correct one. My issue lies in the fact that the original door holes are not visible (replacement panel maybe). I have a template that I used from my passenger side door, I just flipped it around for placement of mirror, but when I drilled my small guide holes I am hitting something and can't get through the panel. I have not take the interipr door panel off but my guess is it is the reinforcement bar I am hitting. Does anyone know the measurements for the holes and where they would be? My thought was that if the bar is there I can use the holes to mount the mirror without well nuts.
