The white jeep is a 3A. The green jeep has an MB tub.

“I have two Willy’s jeeps for sale. One is complete, and ran 5 years ago and the other is a parts Jeep with no motor or transmission. There are extra hoods and radiators. And fenders. I have the pinkslip for the more complete one pictured. They are 1947s the tub on the green one is pretty cool as there is no tailgate. It’s one solid wrap around piece.

Make an offer. I would prefer to sell both at once”
