My '40 1/2 ton got delivered on Friday and I've been going through it to see what I bought. I bought it from photos on CL but couldn't pass it up at the price. The VIN plate is the original judging by it's location and what appears to be the original attachment screws. The VIN is 21KC10 2272 which, as best I've figured a '40 built in Janseville in October and was number 2272 off the line. The engine, however, is stumping me. The code stamped into the boss just behind the distributor is LDA5753b3. I'm not sure what this number is. According to the Tech Tips the number should be between 2697268 and 3665902. If someone out there can tell me what the number is that I can find and where to find the other numbers I would appreciate it.
