If you check a few threads back, you'll see where Corky instructed me on how to do it.
Follow exactly what he instructed... Pull down HARD! In the inside of the mirror mount, there is a pretty big spring pushing two round knobs that hold the mirror in place.
Just grabbed the handle (with the mirror attached) and pulled down HARD. It will come out.
When it comes off, just twist the old mirror off and put the new one on (I wet mine up with soapy water).
NOTE: Be careful when you putting the new one on. I broke one mirror by accident.
