Paul: The one in the engine compartment is the vin or chassis # and the one behind the seat is the body #. Both numbers indicate that this vehicle was built in very early model year 1958. Probably built around the first or second week in August of 1957. If he looks at the very first line on the plate behind the seat there should be a five digit #. This # indicates the build date. For example: If it says 10 08 7, this would mean that it was built on the 10th day of the 8th month in 57. Or, as we would say August 10, 1957. --- On Tue, 9/29/09, singlecabboy <sealingwaxred@xxxxxxxxx> wrote: From: singlecabboy <sealingwaxred@xxxxxxxxx> Subject: [tcb] Singlecab number queston To: "TCB TCB" <tcb@xxxxxxxxxxxxx> Date: Tuesday, September 29, 2009, 12:31 PM A man from Duncan OK. ask what year his single cab is.the plate behind the seat is 254880 and the plate by the engine says 274211.Help will be appreciated.
