Here are some pictures of the car. The tagis off of the front spring. By the part number it is a F41 L35 L36 or L72. The letter code should be CU. It looks like the tags reads COPO....

Black two door Biscayne with the fleet type interior. 6Y27A is the Fleet and Special Order number. Probably was a police car. What's the part number on the spring tag?

Wouldn't the RPO code 9C1 appear on the trim tag if it had been ordered as a police car?

If it was used as a patrol car in police work it will have a 160 mph speedo that says Certified above the odometer, and in front of the radiator a cooler for the engine oil as well as an external supplemental transmission oil cooler. Larger than stock front sway bar and HD shocks and brakes sized for a light pick up.

The only thing that wasn't included with a 9C1 police package was a hot motor. Most had small stone stock V8's for economy since they spent most of their life idling (generally staying hot and running 24 hours a day except when parked in front of the donut shop). Actually this high engine hour count and the fact that they were wrecked generally two to five times in the life of the car is the reason you want to look carefully at a cop car for anything other than a parts car. But if you find a detective or crime scene techs car that hasn't been hit all you need to do is add a big hot motor and you have an "SS" car that can kick it to the curb and take names literally. The 1994-'96 Impala SS was basically a 9C1 car with a hot LT-1 350 that surprised a lot of unsuspecting neo-muscle cars like the Mustang.

The only performance item on a police car were the high speed rating on the tires that allows the governor included on all computer controlled cars to be basically unlimited. The governor is preset at 87 mph on cars with normal tires. The car will not exceed that speed even if you have 10,000 horsepower pushing it; because the computer will not allow the motor to rev any higher. Only cars that left the factory with Z or W rated tires have the governor raised to match the tires (assumes the engine can generate enough grunt to push the car that fast). Just a piece of information to share the next time some ricer claims he was doing 150 mph in his mom's Toyota, or if ordering a new 2016 Z/28 Camaro be sure to check off the High Speed tire box on the order form even if you hate the brand they slap on the car.

The part number on the tag is 3868689 and in the assembly manual that translates to spring code CU.
Thanks for your help, Warren!

Option code 9C1 didn't exist for police package in the 60s. It started in the early 70s, and not on B bodies.

Two doors, four doors, wagons, and ragtops.

I was able to locate and talk to one of the previous owners today! Extremely nice gentleman that shed some light on the origins of the car. It started life with the Public School system in Luray, VA. Then a private owner had the car and parked it after some time. It was at this point in its life that it was vandalized. The engine and transmission were stolen. The man who owned the car then transferred it to a family member. He then sold it and a 1966 Impala to the man I spoke to today. He and a friend of his both recall seeing the car from when it was new. Both men remembered it being a big block car. Not a federal or local law enforcement vehicle like I had envisioned, but I am still extremely happy to know its origins.
