If it was originally a COPO 9511 car - it isn't anymore:

I thought the masks were a molded plastic. But Bill's explanation is spot-on and Lee's pics show it.

There was a COPO Nova Police car package built in 1974 as a small number of prototypes. They were sent to some police departments for testing. In 1975 Chevy made the COPO 9C1 Nova as a police package.

Those Nova police cars were pretty impressive. F41 suspension, heavy duty brakes, etc. A guy i worked with years ago had a 1977 Nova police car he bought at an auction. I rode in that car and it had some get up and go and handled well with that F41 suspension package. Again these cars were rated right up there with the best police vehicles.

Wilma is correct, had a 69 L78 Nova with a BW coded rear (4:56) all the guts of it were gone, but housing cast date and assembly date jived with the car build date. I had a Fischer build sheet and have pics of the rear somewhere. Will hit the archives and see what I can find

Went back in the archives and did some diggin. I attached some pics of my old 69 L78 Nova, specifically the Fisher Build Sheet and rear stampings. Some items to note

The build date of the car was April 26, 04 26 (denoted upper left on BS)
Rear CAST date was April 11
Rear ASSEMBLY date April 18

The rear was more than likely, original to the car as to get a 69 BW rear with matching dates to the rest of the car would be next to impossible. Now on the COPO issue, and the experts can chime in here, boxes 12 and 13 appear to indicate any COPO designation, there is nothing in those boxes.
