Both 1947 and 1948 appear in the ad, so I’m not sure which is accurate. This includes a rear PTO and gearbox.

“1947 Willy’s CJ2a For parts or restoration. Body is in rough condition could use repair or replacement but chassis and drivetrain are complete. Engine needing rebuild has been removed and is sitting in my shed. Full rear PTO turns freely, shifter works fine.”
