“Complete Frame-Off restoration completed in 2018. Motor, transmission, transfer case, front and rear end are original equipment. It has 24,000 original miles. This is a no rust Jeep. It is equipped with an overhead cam 4 cylinder engine. The Jeep shifts great, motor has excellent compression. The transfer case is smooth in low range or high range 4 wheel drive. The frame was sanded and repainted and no rust was evident. New gas tank, brakes, brake lines, master cylinder, hoses and belts. New paint is correct military specs for this authentic Korean War Period Jeep. The interior is new with correct seats. It has the original 24 volt system that works without a flaw. This Jeep has a clean title showing it was purchased from the US Government. Equipped with a new full canvas top. Runs and drives great.”
Meet someone else once who insisted that these were a overhead cam motor.
