Have a friend working on a 57 PU. He cut the cab in half behind the seat and stretched it out. Using a full size door, suicide style, on the drivers side. Sitting on a Suburban frame with a 454 and Th400. Roof has been cut off and will not be put back on. I haven't been to the shop for awhile to see the progress. I'll try to get out there soon and get some pics.
