Mirror placement

I want to mount a mirror on the door of my 65 Barracuda but the PO welded up the holes. Can someone measure or take a pic please and let me know exactly where to drill?

Is it just a screw holding this on or is there some special piece?

Thanks!!

I just bumped the last mirror thread from a month or so back.
