This is an interesting jeep with a variety of upgrades, including a ’45 (MB?) body on a 70’s CJ frame and running gear.  Someone knew what they were doing.  Given the upgrades, this price would be hard to beat if you had to built it yourself.  I hadn’t heard of the Hyrdrovac brake system.

Dual stick transfer case with 2 wheel low option.  Ford 300 in-line 6. Dana 30 front axle with disc brakes.
