had that glass years ago and couldn't give the damn thing away.. know why that was.. every one said they never break.. and ya know what, all the years i have been going through various yars i have never seen one of those windows that were broken.. thats one tough piece of glass.. i did hear one you take it out of the car and lay it like its in the pic that it doesn't fit right again because it warps. not sure how true that is..
