I'm working on decoding this car's fender tag. Many of the options are the same as used for Chryslers and Imperials assembled at the Jefferson Ave Knowing it is a police car, there are unique 3-digit order codes for police items such as special seats-more firm, stronger covers; and other interior items such as a special console and even roof reinforcement for ight bars. Also, a calibrated speedometer. There may even be a remote trunk unlock for quick access to police items in the trunk and the back doors may have special features of no lock or window crank. Does your car have any of these? Have you searched for/found a Production Broadcast sheet--often found tucked in behind the springs of the back seat upright cushion? Do I see a red light transmitter on the dash? Is there evidence of spotlights? More later.
