Resident Metal Head
The mirror is interchangeable(I had to do it with mine). The mirror is held onto a "hockey puck" like plastic, which is then attached to the motor. The mirror slides up off the "puck". However, that was a huge pain in the ass. I just pulled the entire "hockey puck" off by force(it didn't break it the three times I did it), and then got it off the glass after the fact.
