HELP! I backed into a wooden gate that closed unexpectedly and now the mirror (just the reflective surface) has fallen off my driver side rear view mirror. It also looks like one of the small mounting things (shaped like an L) broke. Everything else seems to be working, and the controls to adjust the mirror are okay.

I wanted to try ordering the parts but I looked at the Acura catalog and I'm not sure which parts are the ones to buy. Also, is this something I can attempt to install myself or should I take it in to a shop?
