This has an f-head.

“P A R T I N G — 1947 Jeep CJ2A. located several blocks away from the Recently Closed K Mart on Auburn Blvd just south of The I 80 bridge.

It’s rough. It’s listed as a 1945, but I see nothing to support that.

“True to the story. I inherited my grandfather’s 1945 Willys jeep,with title, and haven’t had the time to get the old girl back on the trail. I have the original flat head motor and three tranmissions, one mounted in the jeep. I will moving in a few months and looking to sell due to the limited space I will have. Please feel free to contact me with questions and I will answer the best I can. The jeep has not ran in about 6 years, but he used to drive it around his old property. The old flat head motor is out, needs work, and he built an aluminum cab that fits over the front seats. I have all the original engine parts.”
