Neither the hood nor the tailgate have a Willys script, so the tub seems to be newer than 1960. The top appears to be for a CJ-5. Not that the steps have been modified and the drain hole removed.

“1960 Willys Jeep CJ3B
Runs and Drives
Has overhead Valve original engine and running gear
Needs Master Cylinder
Jeep is complete
Has aftermarket Cab (maybe Sears)”
Likely has overdrive with extra stick shift.
It’s got a PTO lever (missed that before), but I’m not seeing a fourth stick near the Tranny and TC sticks?
