If you''re trying to nail down what you have, the FSN (Federal Stock Number) is like a bar code. The serial number is unique to the truck, more like the VIN. There may be a way to trace the serial number but the truck has been out of the system so long you probably won't be able to find anything. You may still be able to trace the FSN and it may tell you how the truck was configured since they bought alot of the same trucks.
