It’s a mix of parts.

“This is an awesome running jeep with good brakes, extra set of tires, extra engine and parts, extra frame, extra drive lines, extra axles, extra gauges, and so on.
A 1950 willys m38 body and frame with a willys engine from a cj3a, the rear axle is from the cj and has smaller drums than the front. Titled as the cj3a. The engine was completely rebuilt with new rod and main bearings being .040 and .060 over while the cylinders and pistons are .040 over. The jeep has an extra engine that came from a military generator and has all of the idler and running components still on the engine. The generator went bad while the power plant was still in good running condition.
You have to take it all, 15 years and 4 jeeps involved.
This is well worth more than $4000, so be honest with offers.
Never needed help selling anything, so don’t offer”
