To replace only a mirror and not the housing. You get your fingers around the black backing of the mirror and pull quick to pop the clips that hold the mirror/backing to the motor. You have a chance of breaking it. You line up the backing with the motor to reassemble and push until it clicks and holds on both axis's and the center pivot point. There is a chance to break the glass, try and be careful.
I pushed the glass gently through the couple of holes in teh backing to get the glass off the backing. Then yes.. used one of the "Goop" products to hold it together when done.
