The side vent on the passenger side suggests this is 1959 or later.

“Willys DJ3a, not sure of year. Has 13″ 4 lug wheels i believe came that way from factory. Looks like it has a heater. comes with extra hood. No engine, rolls and steers. No data plates. Been in barn for 25 years.”
13″ wheels might suffest a 1963 model. Major firewall and dash mods. Solid tail with top frame mounts and tall windshield might suggest a Surrey in the beginning.
Steve,
thanks .. I forgot the 13″ was a 1963 model year feature.
