This modified CJ-2A appears to have some later model Free-Lock hubs.

“1946 Willys Jeep. This Jeep only has 11,488 miles since being restored. It’s in excellent condition and a lot of fun to drive. It has a GM V-6 engine, 3 speed manual transmission and a Ramsey Winch. This Jeep has been kept in a climate controlled garage since 1990. Just had the carburetor rebuilt, a new fuel pump installed, the radiator drained with new antifreeze installed, a complete tune up and new Goodyear Wrangler tires installed on mag wheels with a matching spare. The body is in very good shape with no rust and the paint is a 9 out of 10. All lights work including blinkers and the windshield wipers work. This thing will go anywhere you want to go and get you back! It has a 3 speed manual transmission with hi-low range, 2wheel drive-4 wheel drive selector and PTO engage shifter. I have an aluminum top that was custom made for it that is not pictured but comes with it. It runs very good and shifts smoothly. I have the title in hand. Asking $15,500. Located a few miles south of Tyler in Whitehouse.”
