Thanks Bob, yes I understand. I have heard some talk that the letters and numbers I indicate refer to exterior options. I am trying to see if this is true and what my options were.Maybe some of the 3rd generation members can help you with this, but not everything on cowl tags has been decoded. Some of the numbers/letters are internal plant codes. Cowl tags were Fisher Body directives to their line workers as they assembled the bodies. All these tags were stamped as model 114 (V/8) whether the car was going to be or not. The legal VIN was assigned by Chevrolet later in the build process. If your VIN says 114 you have a V/8. A 113 VIN is a six cylinder. The VIN tells the truth! You will not find the VIN on the cowl tag.
