What did you do to your OBS GMT400 Tahoe/Yukon Today?

[the 18th letter]

New heat/ac control came in yesterday and I switched them out today and I have power to the blower again. 3rd shot from the cannon successful. Replacing the dash bezel I knocked the rear view mirror loose. I've always enjoyed replacing rearview mirrors, NOT. Also notice now that my side mirrors dont go up and down anymore so more shit to do smh.

What is this piece called that the metal disc for rear view mirror is attached to? If it’s needed what’s it for? It’s like a really thin aluminum pad maybe. (Apologies if a dumb question)

GM doesn’t show it as a part with the mirror, so it may be something that comes with the windshield to help the glue stick better.
