Definition of Major Component Parts of a Motor Vehicle

PURPOSE: This rule clarifies, by written definitions and illustrations, the seven (7) major component parts commonly used in the reconstruction of a motor vehicle. (1) The seven (7) major component parts which are commonly used to reconstruct a motor vehicle are defined solely for reconstruction purposes as follows: (A) Front-end assembly—An integrated unit consisting of that portion of the body from the firewall forward, that is, hood, both fenders, inner skirt of fenders, radiator or core support, and grille; (B) Front clip—All parts of the front-end assembly plus complete cowl. It may include instrumentation and steering column. It requires cutting of vehicle floor and windshield post; (C) Cab—The passenger compartment of a common truck. It is a one- (1-) piece sheet metal construction which may or may not include glass, instrumentation, steering column, and seat; (D) Rear clip—The complete rear sheet metal assembly formed by severing the vehicle across the floor and either through the windshield post or through the rear window post; (E) Cowl—The sheet metal formed by severing the vehicle across the floor in the vicinity of the front seat and severing the windshield posts. It does not include parts forward of the firewall. If a cowl is included as an integrated part of a front clip, front-end assembly, or rear clip, it will not be considered a major component part for the purpose of determining the total number of the major component parts used in the reconstruction of a motor vehicle; (F) Frame—The steel basic structure which runs the entire length of some vehicles and onto which the suspension parts are bolted to the lower side and the body is bolted to the top side. Unibody vehicles do not have this type of frame; and (G) Body—The shell, either of a unibody or frame-type passenger vehicle, which consists of a one- (1-) piece, integrated sheet metal construction extending from the firewall back. The body includes a cowl but not a front-end assembly. It may or may not include an interior, doors, and deck lid. It does not include a frame as defined in subsection (1)(F). (2) The major component parts which are commonly used to reconstruct a motorcycle are defined solely for reconstruction purposes as follows: (A) Frame; and (B) Transmission.
