The mandatory standard now covers these eighteen components and their replacements on the covered passenger motor vehicle lines: (1) engine; (2) transmission; (3) right front fender; (4) left front fender; (5) hood; (6) right front door; (7) left front door; (8) right rear door (if present); (9) left rear door (if present); (10) sliding or cargo door(s); (11) front bumper; (12) rear bumper; (13) right rear quarter panel (passenger cars); (14) left rear quarter panel (passenger cars); and (15) right side assembly (MPVs); (16) left side assembly MPVs); (17) pickup box, and/or cargo box LDTs; (18) rear door(s); (both doors in case of double doors) decklid, tailgate, or hatchback (whichever is present). In most cases the full 17 character VIN of the vehicle itself must be placed on the original component. While the number can be stamped into the component, most manufacturers are applying a counterfeit resistant label that contains the VIN. The label will self-destruct if it is removed. The number is to remain with the component until the component ceases to exist.
