I'd hazard a guess that it's a dual exhaust 440HP equipped (with HP transmission) Chrysler where the single exhaust non-HP was the only available listed 440 OPTION

The conversation about this car on the C-body forum is amusing.

I like that they included a picture of their house

Do tell

Are you guys for real? What don't you get about this car? Baffled? No something else maybe...There is nothing "fishy" here with this car.
Chrysler Newport's were not regular cop cars, so a C body cop car would have to be a special order car. Some one had connections back then to get this built.

A sales order # K15898 "K" police sales order number prefix plus a Y39 for special order equals a police car!
This is a Jefferson Rd plant car. Little is known about this factory's fender tag protocols as they differed from plant to plant. One of you experts must have have studied these tags? Well?
How about the 1972 police car literature?
Does it show the Chrysler Newport?
What we do know is those engine and trans code are a for a special engine and transmission!
T code is a 440 but the E99 special order 440 supersedes the "T".
D99 is a special order 727
Very special Police BOB car. Big Ole Boat
Different for sure
Disc brakes
Cruise control
no trans cooler seen
Overspeed switch on the a/c? can't see it but it will be on the line going to the condenser on the pass side
no elect ignition seen
coolant recovery system
N51 max cooling pkge so there may be a trans cooler hiding, ps cooler? oil cooler?
certified speedo?
Even though i don't want a car i may have to buy this to flip.
Way too significant to pass up, calling the seller later today to check on the speedo and paperwork. Leaving tomorrow for MO.
Checking on the one way rental.
