Tom,
I don't know what the hole spacing is on the Mustang style mirros. My car has the "pointed" body color mirrors that were so popular on Fords in the early '70s & installed on many Panteras as an upgrade to the chrome mirrors. The hole spacing on those mirrors is very wide. I would guess the Mustang mirrors are similar, but that is just a guess.
I have a set of GT5-S style Vitloni mirrors that I plan to install someday, the Vitaloni mounting base is not long enough to conceal both holes of the Ford mirrors. My plan is to just install a flat head screw in the exposed holes until someday when I have the car repainted.
The Southern Rods & Parts web site does not provide mounting dimensions for the Carolina mirror, like I wrote earlier, that's a dimension Chris will need to provide.
your friend on the DTBB, George
