I am attempting to better id or de-code the vin on a 60 truck. The VIN is 0C369J107010. I have it all de-coded but the Truck Type, which is the 9. The side of the truck fender trim says Apache 30. Why would it say 30 if it is a C36 Truck? It is a dually truck with a 10Lx8W box. Any help appreciated. Gene
