I'm looking at a 1963 Plymouth B-Body.
The VIN says Model/Series: Police Code 9 in the Vin.
Its a Big Block 2 Door car with 4-Speed

What does the Model code Police contains?

I thought K was the second letter in the VIN designating a police/taxi.

FYI, Here is a pic of a 1964 Savoy Police car. Sorry, but I don't have the the VIN for the car. The 393 Body code on the tag, denotes that it is a V-8 4-door Sedan Police Car.

A 62-65 VIN with Code 9 at second letter indicates Model Police

K is on later years

In '64, Y9 also indicates police or taxi service when the engine code is not 08/09. When the engine code is 08/09 and Y9 is present that indicates it's an aluminum front car.

If anyone wants a crack at decoding the police fender tag, then have at it...

Super rare cars, have never had a 63 but a 64 Plymouth I had had sway bar and 11 inch brakes. Would be very very surprised if it was a factory 4 speed car, most cop agencies got auto's and if they got a stick it would be 3 on the tree. Any fender tag pictures?
