I'm helping my son and 3 of his high school friends restore 1984 -85 19' Supra Rider that's missing the rear seat back and side arm rests. If anyone has a photo of the frame of the rear seat back I would really appreciate your sharing it with me. We would like to see it with the seat bottom removed or opened to see how it's put together. We don't know the exact shape and how it's attached to the bottom seat frame. Thanks!
