The Vehicle Identification Number (VIN) is located on a plate attached to the left front of the dash panel so it can be seen through the windshield when you stand beside the vehicle. All vehicle identification numbers on the 1979-80 models contain 13 digits. The letters and numbers in the VIN digits can be interpreted according to their positions in the sequence as follows:
- Truck line
- Wheelbase and Gross Vehicle Weight (GVW)
- Price class
- Body code
- Engine code
- Model year
- Transmission code
- Trim code
- Followed by a 5-digit sequential (serial) number
On 1981-93 models, the VIN number contains 17 digits which are composed of letters and numbers and can be interpreted according to their positions in the sequence as follows:
- Manufacturing country
- Vehicle type
- Type of seat belt system, weight class of truck/multi-purpose vehicle.
- Vehicle line
- Trim code/price class
- Body type
- Engine displacement
