Mine broke too, and I was lucky enough to find a Roadmaster wagon in a yard, and took the whole upper rear seat. I don't know for sure, but I can't imagine earlier model wagons would have that part. The earlier models of our cars (91-4, I think) have a metal hinge for the fold down part of the upper seat, and its different. I think you'll just need to keep looking. If you don't mind spending retail money, check out car-part.com, and I'm sure some junk yard will have an upper seat for sale. Transferring your upholstery is easy, and only takes a few minutes.
