i've got an SM 465 tranny for sale in Salt Lake City, Utah. It is from an '85 Suburban. When I bought the tranny it had the long fine shaft in it. So, I swapped that out for the short coarse shaft. While I was replacing the shaft I had it drilled and tapped so it is ready to mate up to your transfer case with the help of an adapter plate. I also replaced the bearings, syncros, and third gear (with the back cut teeth) as I hear they are notorious for popping out. I would like to get $300 but will consider your offer.
