Except for the grill, rear fenders and Rear diff, it looks like my 1939 3/4 ton. The 1/2 ton would have the axle over the springs. The 3/4 will have the axle under the springs. The 3/4 ton would have had an additional short closed drive shaft in front to make up the additional 10" or so of bed length. (kind of like the GMC long bed). Don't want to violate any posting regs, but if you are trying to return this vehicle to original, I know where you can get a 1940 3/4 ton differential free. Send me a private message.
