You probably have them off by now. I couldn't find a link but when you fold the mirror back there is a piece of bailing wire that keeps the mirror cover on. When it is unclipped, let the mirror go back to the regular position and the cover should come right off. Sorry for the late reply. Haven't checked this thread in awhile.
...and if you're trying to slide the cover off the facelift design, it's not a wire but
a horseshoe shaped clip (STICKY topic)
