Just completed this repair on my original driver's side mirror. Went pretty smooth except for one small chip in the glass from when I was trying to get it off. I ended up using various sides of a trapezoid shaped utility knife blade to gently pry it off. Req'd some patience but it came off eventually.
Tomorrow I'm going to install the new pass side mirror (Corvette Central, quality seems pretty good) that's been sitting in my garage in the box for months. I was dreading the install since I thought that backing nuts would be required inside the door. I finally looked in the hardware bag tonight and it looks like there are anchors included that do not require access from the back - cool! Is this how the originals were installed? Assuming this method is plenty secure? The other nice thing about the CC mirror is a paper template is included with explicit dimensions regarding where to drill.

Hi Dave. It's hard to believe that any other method besides passing through the door skin and securing with a washer and nut would be stable enough, though I'm not an expert. I'm converting my single driver side mirror on the '75 to a pair of sport mirrors and I've seen this discussion on the forum before, mentioning the need for reinforcement inside the door under the nuts, but I see no way to access that area, just the 2 holes (3/4") to reach the nuts. My only plan is to add as large a washer as will fit through those holes before the nuts. I'll hope that if anyone knows better that they'll speak up 'cause I'd hate to think that road vibration might cause damage to the fiberglass due to the weight of the mirrors. Let us know how the mounting works out.

Iirc, the factory installed mirrors have a backing plate on the inside of the door. The dealer(and aftermarket) installed, pass side mirrors did not....they used nutserts....sorta like a drywall anchors. For the sport mirrors, you do need the extra backing on the inside of the doors, but for the plain-jane, manual mirrors, the nutserts work just fine.
