* Driver's side dashboard: This is the most common location. Look on the lower portion of the dashboard, often visible through the windshield. It might be on a metal plate riveted to the dash.
* Driver's side doorjamb: Check the edge of the doorjamb where the door meets the body of the truck. It might be stamped into the metal.
* Engine compartment: Look for a metal plate attached to the firewall or another part of the engine compartment.
* Under the hood on the radiator support: This is less common, but possible on some models.
* Title or registration documents: Your vehicle's title or registration papers will also list the VIN.
If you can't find it in any of these places, you may need to consult a local DMV or a mechanic who specializes in older vehicles. They might have resources to help you locate it.
