1. Dash Panel (Instrument Panel): This is the most common location. The VIN is usually stamped on a metal plate riveted to the dashboard, typically near the lower left corner from the driver's perspective. This is the plate you're questioning.
2. Driver's Side Door Post: This is a stamped VIN, *not* a plate. Look closely at the edge of the door jamb where the door meets the body. It's often partially hidden by the door's rubber weatherstripping.
3. Engine Block: The VIN (or a partial VIN) might be stamped on the engine block itself. This is less reliable as engines could be replaced. The location varies depending on the engine type.
Why your dash plate is suspect: If the dash plate VIN doesn't match the door post VIN, it's almost certainly incorrect and likely a replacement or a fabricated plate. The door post VIN is generally considered the most reliable as it's less likely to be changed.
What to do:
1. Check the Driver's Side Door Post: Carefully clean the area and examine it closely. If the VIN on the door post is clearly legible, this is your definitive VIN.
2. Compare the VINs: If you can find a clear VIN on the door post, compare it to the dash plate. If they don't match, the dash plate is incorrect.
3. Title and Registration: Check your car's title and registration documents. The VIN should be listed there.
4. Professional Inspection: If you have doubts or cannot locate clear VINs, consider having a professional automotive inspector or a Ford specialist examine your car.
In short, don't trust the dash plate alone. The discrepancy with the door post VIN strongly suggests the dash plate is not original to the car.
