“I don’t know much about these Jeeps. I recently acquired this Military vintage Jeep from the previous owner who obviously put a lot of effort in restoring this vehicle both mechanically and body. A few after market refinements were put in place including: electric fuel pump, alternator, turn signals, back-up lights, gauges, exhaust. Looks like the entire drive train has been gone through. It starts and drives great, 4WD works, brakes well, solid steering, good clutch etc. Looks to have a full floating rear axle, front locking hubs, wheels and tires in great shape.
