Hey regmudd, I too remember reading and article (with pictures) of converting a small to large back window on a tri-5 series truck. I'v e searched all my old magazines and other articles and can't find it now. That's what I am now finding myself doing with all my spare parts and tools, too. Can't find what I'm looking for sometimes. I think, however that in view of the many fine comments from other Stovebolter's that I may just leave it a big window and trust that it will turn out well. Thanks you and all the others for your help
