If they filled the rivets properly and put a couple coats of black paint on it, it would be less obvious.
My point is, I see no problems with the codes on the tag. Often when a tag is reproduced, something that was never done at the factory is presented on that tag that makes it an obvious reproduction. e.g putting hounds tooth interior in a convertible that's not a Pace Car. That is what I though William was referring to and did not see it.
No real reason to have a fake tag on this car except for a more desirable color and interior, as 1968, 1969 Van Nuys, and early 1969 Norwoods have no performance options encoded on the trim tag.
