“Clearing out my garage before winter. Up for sale is a complete rolling chassis from a 1957 Willys Jeep CJ3B. Basically it’s the frame, front/rear diffs with wheels, suspension. There is NO motor, although I do have the original transmission/transfer case combo as well as the drive shafts. I was planning on doing an engine swap, so I also have an Isuzu 1.8L diesel as well as the Isuzu MUA5 manual transmission/transfer case. I went through the entire engine and also resealed/ repainted it. I have a new starter for the diesel engine as well. I also have a set of front/rear narrow track diffs from a CJ5 for it too. As for other parts from the CJ3B I have: the hood, front grille/radiator, seat frames, some electrical parts, gauges, fuel tank, lighting and some other miscellaneous parts. Selling everything together for $500. If you are interested in certain parts separately, let me know.”

It’s listed both as a 1953 and a 1954.
