I did change the paint and trim codes on the new tag..
I fully understand why the "purists" get pissed off about it, and I'm really on their side..
Because there are people selling fraudulant rare-optioned Camaros and getting away with it.. But in my case, I'm not frauding anything when I'm completely open and am telling everyone exactly what I've done.
Anyway. GM did such a sh!thouse job at documenting their cars back then. It's no wonder the frauds are everywhere. That pisses me off too.
