This appears to have one of the late model Worman Jee-Cabs. Not amnion these around. The rear of the top looks custom to me.

“1954 Willys CJ3B. Great project. Extremely solid and straight. Has arctic hardtop. Engine and seats are missing but everything thing else is there. Find another 134 “F” head or perfect for a v6 or V8 conversion. Last driven in 1976. Stored under a carport for a majority of the time since then. It will be hard to find a better CJ3B to restore than this one. Has not been abused or molested like a most. If the ad is up it’s for sale. No trades too many projects already.”
