The service parts identification plate, 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 plate lists the vehicle serial number, wheelbase, all Regular Production Options (RPOs) and all special equipment. Probably, the most valuable piece of information on this plate is the paint code, a useful item when you have occasion to need paint.
