Chassis Parts Manuals give exploded views of the various parts of the car with corresponding part numbers. These exploded views show in detail the individual components of most parts on the car. Each component has a identification number. These "part numbers" can then be used when ordering parts. Using parts numbers is much more accurate than merely providing a description of needed part, and cuts down on the possibility of receiving wrong parts. Most chassis manuals also include a section on model identification with beginning serial and engine numbers. Parts of the car included in the chassis manual include; the engine, transmission, fuel system, exhaust, cooling system, electrical system, brakes, front and rear suspension, steering, instruments, fenders and sheet metal, frame, and rear differential.
