You've never seen a fender tag with body color and roof color posted on different lines? Is that what you are saying? I'm really unclear.
What is out of alphabetical order here?

That's what the tag MIGHT have looked like. I didn't rearrange anything other than to put break where they would normally occur. I see one or two things, now, that might be a little strange, but, I'll keep that to myself.
My December 1, 1969, Windsor built, 1970 Swinger 340 has two FY1 paint codes listed on the tag, one for the body, second for the roof.
I will tell you this... 69CoronetRT is one of THE most knowlegdable people when it comes to fender tags, BAR NONE!
Here's an earlish 70 Duster Hammy tag for you... note the two paint codes.
