Given the slat grille, maybe this is a mix of parts? Gotta love the windshield.

“For sale 1942 ford jeep body in bad condition no title has original engine trans and differentials. It ran and drove about 15 years ago and has been sitting every since. It is a project but it is somewhat rare since it was built by ford in 1942 when jeep could not keep up with its military contract and the contract was split up to fulfill the military needs. The windshield was put on it by my father it was from a vw bug it does not belong on it . the price is $700.00 obo if interested please call five 20- four 19- 498zero thank you.”
