Parts Marking

To deter vehicle theft, certain major components are marked with the vehicle identification number (VIN). Original

parts have self-adhesive labels. Replacement body parts have generic self-adhesive labels. The original engine or

transmission VIN plate is transferred to a replacement engine or transmission and attached with break-off bolts.

NOTE: Be careful not to damage the parts marking labels during body repair. Mask the labels before repairing the part.ProCarManuals.com
