Hi,
that is what I meant. It is some sort of stuff bonding the hinge to the glass.
I am sure that the dealer wants to sell you an new glass assembly, and for him, the bracket is part of that.
He can not sell you the bracket by itself.
So you probably will be out of luck.
I still would try an auto glass place. They may / may not be able to fix it.
Take care and keep us posted. Eggert
