The bottom hole on the reinforcement plate is threaded. Perhaps running a bolt with a sharpened tip through the hole into the fender enough to dimple it would mark the spot to drill the finder. This would insure that the mirror bolt will thread up correctly with the plate.

Use a spring punch through the upper hole to dimple the fender. Then mount the mirror with the "threaded" bolt to fine-tune the location of the upper hole. It may not be exactly on the dimple.

Just a idea. I haven't tried it.

My truck's po drilled from the outside without using the reinforcing plate to mark the location. This resulted in an extra upper hole in the reinforcing plate and buggered threads on the lower hole.
