The transfer case is a Rockwell. It is a T221. There were several variations '62 to '69. Shift pattern for the 2WD 4HI Neutral 4LO. the 2WD is closest to the firewall, 4LO is closest to the seat. Torque Ranger from Advanced Adaptors is another possiblity for an overdrive with the SM465. Lots of work to do it.
