I have a jeep titled here in Idaho as a 1940 Willy's Jeep. From what I understand, Willy's brand Jeeps were not in production until 1941. The VIN is a state assigned number that they riveted to the firewall, and the motor is not original. I can't seem to find any information on ways I can tell what year my jeep is or of any of it's history via documentation of this era of willys that I have been working to fix up. I've just been hitting dead ends, please help!!
