Thanks Sir Nuke, I think that info was very beneficial because I now have insight on getting the mirror off. When I get the mirror of the mounting shoe , I can then can take my time to get the stock mount off. I am not just replacing it with the probe mirror but the hole mirror console. On 89 GT,s they have a hole console that attaches to the ceiling never attached to the window, looks perfect when slid on. Had tried taking it of like 2 months ago was being really carefull but still I made a hairline fracture about a inch. Not bad cant feel it on either side and doesnt leak I did checks a never had a leak even when it rains. It is really small, I will cover it up with a vinyl strip since I wanted one anyway, since it is not leaking and when I cover it up it wont be noticible I dont see a reason to replace the window. I had replace a sable mirror a few years ago and remembered it was glued on but didnt remember the hole procedure. Wish I would have had asked earlier cause then with my window would have been perfect still, but that is part of learning. Sorry for the long post but thanks, I now know what I am looking for and feel I will get it off.
