What I see here is a standard 318 car and not a factory police package car, I'm not saying it isn't a Police Car.
If a department buys a car and uses it then it is a police car.
So if this is a Police Package car, PK21 it would have a Leece Neville alternator and voltage regulator.

Alan this is incorrect, and it's understandable as you are used to dealing with C.H.P. "package" Polaras.
There was no "police package" until I believe 1970, the "package" would be stamped on the "fender tag" and not the VIN in 1970.
Before 1970 police fleet vehicles, specifically named by Chrysler in the option book and the police brochure as,
POLICE SPECIALS, they could be ordered with a variety of police options.
The Plymouth models were:
Patroller, Pursuit, and the
Emergency Wagon. PK is the VIN designation for police fleet, which means the car has all
standard "police options".
The standard alternator on a PK "Police Special" fleet vehicle; Patroller, Pursuit or Emergency Wagon was a 46 ampere Heavy-Duty Chrysler Alternator, with standard regulator. You need the Broadcast Sheet to know 100% what your car was equipped with. Unless it was an agency/State special order fleet package A.K.A "C.H.P. Specification".
Optional was the 60 ampere Chrysler alternator and a 65 ampere
Leece-Neville with Transistorized Regulators and Silicon Rectifiers.
These are optional equipment,.... and not part of a "package".
This car is definitely a Plymouth Police Pursuit. With
standard police specifications.
I can list all the standard specifications, and all the optional equipment for a "police special", Patroller, Pursuit, and Emergency Wagon if anyone is interested.
Non A/C is somewhat rare.
White car,.....likely OSP. Very rare today.
