I have the 2 round pieces of glass that fit in the corners on the back on some (brazil, mexican?) kombis. They are the ones that bend around the corners. I suspect those to be a hard to get item, so if anyone would want those, drop me a mail with offer. I have the other glass as well (this was a bay with small windows on the sides) but that can be made cheap, no idea about the round ones.
