This is a project, but includes a GPA motor.

“I have a 1943 Willys jeep for sale, in process of restoring but moving forces sale, frames is excellent, normal rusted out areas for body, but easy fix, engine does turn over, transfer case is good, still some orginal paint on all parts, “F” stamped transmission and transfer case, GPA motor, rare engine. DOD is FEB 19-29 1943….Have title that matches orginal body/Frame. Engine was overhauled in Topeka KS 08/24/1945 with all STD bearings so you know it wasn’t abused. Has 4 Combat rims
In photo it has cj2 headlights but previous owner just mounted them there, not buckets, has hinged brackets under hood.”
