I'm not sure I'm posting in the right place, so sorry if not. Yesterday we had a close encounter with a larger truck and ended up with a smashed wing mirror. I only need the glass part replacing (it is light sensitive and heated) but I'm told that GM only supply complete mirror units. So I've been quoted nearly £800 plus tax for a replacement. That's a vast sum for something I don't need. Do any of you know if I can get the glass piece from an aftermarket source? Or do any of you have a second hand mirror you can sell me? I have a 1998 Suburban K1500 and it's the right side that's damaged (as we drive on the wrong side of the road). Thanks. Please post a reply.
