In the comments someone was trying to figure out about the fuel connection ...and i was wondering about the radiator.
Must be a fake motor that contains an air cooled engine with a fuel supply.
Radiator, motor, transmission and transfer case all come out as one unit in those models.
I also noticed comments about the wheels only having two studs and nuts. Real military Jeeps had left handed threads on the left side and right hand threads on the right side. All the nuts came off like right handed threads.
