The service parts identification label, commonly known as the option list, is usually located on the inside of the glove compartment door. On some vans, you may have to look for it on an inner fender panel. The label lists the vehicle serial number, wheelbase, all Regular Production Options (RPOs) and all special equipment. Probably the most valuable piece of information on this label is the paint code, a useful item when you need to match the vehicle's original paint.
