My mechanic has been taking care (last 25 yrs), of a 1942 MB Korean survivor. The owner was out driving the jeep when he thrown a rod. Does anyone know where to find a rebuilt motor for his jeep. Everything's stock including the 6 volt wiring. If not a rebuilt motor, does anyone know who would have a used motor in good condition. They are looking for a motor if possible that is a drop in without having to rewire to 12v and keep the same era if possible. Any info is appreciated. Thanks.
