Doris Day '69 Ragtop

A couple of years ago I bought a red '69 ragtop Barracuda, reportedly the same car used in filming the Doris Day show. The only hard evidence I have to that end is a CA tag ZCL-010 (with '69/'70 reg. stickers) matching the tag on the car in the show.

I also know that the car was owned by a police officer in Chicago, and ended up here in SC with a relative of his, who I bought the car from. Prior to that, I have nothing but the plate.

I'm trying to pull together the paper trail back to Doris Day, but am not having much luck so far. Was wondering if anyone had any information, or has had any luck researching this type of thing?

Thanks
