Help with a California Black Plate

[BGlover67]

I picked up this California black plate about 8 years ago.  The guy sold it to me via eBay, and said he wasn't sure where he got it, but that it was on his garage wall for 30 plus years. Can anyone help me identify which dealer it corresponds with?  Having the Downtown Ford ring on it, obviously doesn't mean it's from there, but it would be cool if it were.

I did research that black plates were originally used in California from 1963 to 1969, the golden years in our hobby.

Wow, Ai is truly going to take over the world.  I asked Google's Ai and it gave me a website to look up the '2000' code (02000) and it came back as Downtown Ford, yeah!

This is the website FYI.
