Well the truck just got delivered. The VIN plate is right where it's supposed to be and it's definitely a 1940, 21KC10 2272. The rear end/drive shaft were replaced with an open drive line. At this point I'm not sure what kind, but it appears a little short since the front of the rear tires seem too close to the fenders. Although this could be because the rear fenders are off a '47 or later truck. Someone put it a solid steel floor in the bed so that's going to have to come out. I'll also be in the market for new running boards and front fenders. I've already located correct rear fenders and Mar K has the entire bed and bed wood kit. The original seat frame is in the bed so I'm going to have to get an upholstery kit to do that. The engine runs strong but I'm not sure what transmission is in it. I'll take some photos and post them when I get some time. It does start right up and runs well. Looks like there might be a little oil leak from the pan but I'll have to get under it tonight and see what's there.
