My understanding is the use of the engine number went away after '55. It's the seller's responsibility to make sure everything's kosher. Often times on these old rides the authorities aren't too strict about requiring the VIN to be on the original data plate so you MAY be able to buy a repop plate and stamp the number on the title on it & mount it to the truck.
FYI, if it was me I'd first run the number on the truck's data plate through the police to make sure you're not buying a huge problem.
