Ok so a dead tree branch and a windy day caused me to lose the back window of my 92 acura legend. I have been having a hard time finding a replacement. I've called the local auto glass companies and so far they all said I would have to call a junk yard to get the window but I've have no luck at junkyards either. So my question is , are there any other cars with a rear windshield that also fits my car that I can search for? Or does anyone have any ideas where I might find a back glass? Any and all help will be very appreciated.
