This is the problem I've seen.
Three cars, all Z's, all should have the same colors. Did the white fade to yellow or vice versa? I think there's normally 3 stripes, but maybe there are only 2 for this part. Is Dave's car's 3rd stripe for something else or are the other 2 cars 3rd stripe just faded or rusted away. Or was there a coding change midyear (I doubt that). Just hard to be sure.

I have not seen a definitive answer, hopefully somebody else has!
