How to fix a broken aero mirror base

[175K911]

When I took my aero mirrors off to get the car painted I accidentally broke one of the two locating tabs off the base of the drivers mirror. After getting over being mad at myself I took a close look at options. The tabs are relatively soft pot metal so I figured I had nothing to lose trying a repair

Located the center of the broken piece, drilled a small pilot hole about 1/4” deep, being careful to keep the drill bit as centered as I could.
Followed that with an 1/8” drill bit.
Got out my tap set and tapped threads into the drilled hole. Sorry, don’t recall which size I used, but I’d selected it to work with a metric screw I had.
Ran the screw into the hole to verify it would work.
Pulled the screw back out to put 2 layers of heat shrink on the exposed threads.
Ran the screw back in with some red Loctite.
Mounted the mirror like nothing had ever broken.
