I have heard that someone makes a conversion kit allowing you to put a "BIG BACK WINDOW" in a 55-59. Anyone have any information on this?? thanks mac
did it Mac, I don't know about a kit but I converted mine last winter using a donor cab with a big back window. Took a lot of drilling of spot welds, etc. I separated it at the natural joints up the door jams and along the roof and jig saw cut it below the window at about the top of the box. I used an air powered tool to put a kink in it so I could overlap and weld on the joint.
