Maybe so, bit it's got the 69/70 CA registration stickers on either corner, is verified as having come with the car when it sold in 70, and matches the plate in the shots from the show. I'll need to look at it again to verify the color scheme.
Wow! Thats cool. I would not have expected them to use real tag numbers on the car in the show. Now people hold their thumb over a camera lens so their tag number doesn't show up in a photo on line. I guess that wasn't considered a security risk 50 years ago. You are very lucky indeed that the tags were kept with the car through the various owners around the country.
