The standard non-illuminated mirror is just held on with two tits pushed into the fiberboard. They come off with no problem. Besides if you break it there are plent of them in the boneyards. GM used them on everything. Now if its the illuminated mirror than those are just held on with a couple of tiny Phillips head screws. You'll have to cut the wire to fully remove it but that can be resoldered after its been recovered. Nothing to worry about on either mirror.
