“Early CJ6 Willys Jeep Koenig Ironworks Hardtop. The doors and outer roof skin have been media blasted. I have all of the hardware for the door sliding windows and sliding windows for the side panels. The rear hatch is missing, I never had it and dont know where it is. Seeing that it would basically be a flat piece of sheet metal with a top hinge it would probably be pretty easy to make one. The top is in reasonable condition, and I believe would only need some minor repair, new glass, and a rear hatch door to be 100%. I am asking $250 obo.”

UPDATE: **SOLD** Was $650.

Appears to need some glass

“Cj2a Willys Jeep hardtop talk about rare to find 650 or best offer. Also willing to trade for M37. Dodge Power Wagon parts”

It looks like this might fit a CJ-3B.
