Years ago I had to replace a Talbot mirror on my first '77 911, the former owner exchanged the large Porsche ones with the small Talbots. Anyhow, I can't recall these mirrors are that expensive. There were good and they had no vibration and the view was excellent.
$400 is way too much for a mirror and your fix seems to be working. Good job!
Now, as someone mentioned before - what's up with that light fixture?
