I moved my drivers side power mirror yesterday and it fell off. The black plastic bracket that is mounted to the inside of the mirror cracked in half. I'm trying to figure out what that part is and if it is available by its self or if I have to order the whole mirroe assembly?

 

Looks like you have to "Buy The Farm", so to speak. Here's an illustration of the '92 Accord Miror detail.
Pick out what you need.

Looks like you can buy seperately everything BUT the structure center section. Sorry

Try EBay, or do a "GOOGLE!!'" search, you may scare up a used one or an aftermarket replacement.
