You don't really have to take the windshield mount off to change the mirror , there is a small screw that holds the mirror to the windshield mount , it is inside of the "stem " that the mirror is attached to .The screw head is slotted , use a very good small slotted screw driver , work with it for a bit or it may come right on out. You might apply a little heat ( not a lot so as to not melt anything ) which will aid in the removal of the screw , it is long but very small diameter . Good luck , maybe give it shot before trying to unglue the windshield mount.

And about the time you get the replacement one just about tightened, the old windsheild mount should fall off easily into your hand, replacement mirror and all.
