Q: Vehicle ‘Tracking’ Numbers For 1968
What are the important numbers for my car and where are they located?
VIN (Vehicle Identification Number)
Assigned to a Body once it has been scheduled for build (Body in White) prior to Final Assembly (while at Fisher Body). This 13-Digit Number included the Division(Chevy, Pontiac, etc.), Series, Model, Year, Assy Plant, Engine (V-8 or 6cyl). The last 5-Digits were the specific Serial Number. The VIN was stamped into a metal tag riveted to the top LH side of the Dash. New for 1968 was the stamping of the VIN (minus Series & Model) onto the Engine Block and onto the Manual Trans Case. This would have occurred at the Vehicle Assembly Plant just prior to (or during) installation into car.
This was the consecutive body number as assigned by Fisher Body. For 1968, there were 2 Assembly Plants, LOR (for Lordstown, OH) and LOS (for Van Nuys, CA). This number was stamped onto the Firewall Trim Tag and will appear anywhere from a 2-Digit number up to a 5-Digit number. This number will also appear on the Broadcast Sheet. There is no consistent (numerically consecutive) pattern between the VIN and Body No.
ENGINE UNIT NUMBER
A 6-Digit Number was stamped onto the front RH face of the Engine Block. This was a tracking number used for sequencing an Engine to a specific car. All V-8’s started with a 2 while the 6-Cyl’s began with a 6. This number was most likely stamped at the Engine Assy Plant prior to delivery to the Vehicle Assembly Plant. Also found on the Car Billing History Sheet and on Owner Warranty Data Plate. No consecutive connection to the VIN as this number was not unique to a specific Model.
Once a car was ordered, an Identification Number was created and routed through to the Assembly Plant for scheduling. This 6-Digit number was entered into the Broadcast System at Fisher Body and the Final Assembly Plant. This number is found on the Broadcast Sheet and along the bottom of the Window Sticker. There is no direct sequential connection between this number and the VIN although the Identification Number is usually higher than the VIN and does climb higher as VIN does.
Found only on the Broadcast Sheet, this number was used within the Plant as assigned by the scheduling dept. Usually a 3-Digit number with no sequential connection at all to the VIN, Body Number or IDENT. Number. Perhaps assigned in batches and/or daily.
A 6-Digit number proceeded by a letter. Used for Billing purposes and found only on the Car Billing History. No connection to any other vehicle number.
