Appears solid. Nearly ‘all’ original.

“Up for sale all original 1946 Willys CJ2A. Runs and drives super smooth. Recently work done on all oils replaced, transmission gasket changed etc. Very powerful torque, easily goes 45 mph, it could go 55 mph but didnt try it. I restored it partially after getting from a ranch sale last year it was used on the farm and around town as a work horse. Great original patina and sound. 4 WD works nice as well. I wouldnt change anything on this beauty. Electrical bulbs might need to replaced, thats all.”
