The part of this that first caught our eyes as unusual was the shift linkage for the transfer case and transmission. Most 2 speed Chevrolet CMP transfer cases we've seen have a tower that is mounted to the transfer case crossmember and pokes up through the floor. it has multiple rods and interlocks and requires quite bit of fiddling to set up. Bob detests the fiddling. It lets you select 2wd, 4WD High, 4WD Low or neutral for winching.
This setup will only let you have 2WD or 4WD Low. The same movement of the lever that engages the front axle also selects low gear. This case does not have a PTO fitted. In this style linkage winching (or other transfer case mounted PTO functions) are controlled separately so I believe could be engaged while the truck is in gear.
This transmission and transfer case also explain an engine cover with shift plate that came with my C60L (with REL body) that made no sense with the "normal tower shifter T case on the truck.
