Listed as a CJ-2A, it looks more like a CJ-3A. Oddly, this has a circular fuel inlet, but I can’t see anything else that makes me think this is some kind of 1) DJ body or 2) replacement body.

“Jeep Willys CJ-2A for sale, original engine and transmission I believe. Possibly a 1948 (missing tag on firewall for identification.) No title – but none needed for a 1948 as far as I know. $4800, and buyer tows from the yard.”
