Well, while the short answer is obvious, I will eleborate... I had one stored in my garage for years. Walking by it, even bumped it a few times. I had gotten it in a deal with other glass and thought it was nicer than the one in the car, so held onto it. When the time came to do the new gasket I figured I would clean both and use the best one. It was sitting on styrofoam. Went to pick it up and a corner touched the concrete. It was really kind of amazing how it was a lot like watching when they implode a building and it ends up mostly in a pile of rubble.
Anyway, to the OP. Snake- That price is ridiculous. At least around here, these are still in junk yards and they are usually in really decent shape. Unlike the front which always has delamination fog around the edges. Wish I was closer and had not already put my new gasket on. I'd love to have a rear defrost.
