1. Driver's Side Dashboard: Look for a metal tag attached to the dashboard, usually near the lower left corner. This tag will contain the VIN, as well as other important information like the vehicle's model year and assembly plant.
2. Driver's Side Doorjamb: On the edge of the doorjamb, there's a metal plate (sometimes embossed or stamped into the metal itself). The VIN will be stamped onto this plate.
Additionally, the VIN might be located in these places:
* Under the hood: Sometimes the VIN is found on a metal tag attached to the firewall or radiator support.
* Spare tire well: The VIN may be stamped on the spare tire carrier or on the well's metal.
Important Note: The exact location of the VIN on a 1968 Cadillac may vary slightly depending on the specific model and body style. If you have difficulty finding the VIN, you can consult a Cadillac repair manual or contact a local Cadillac dealership for assistance.
