97904 is the Dupont paint mix formula number for Tiger Gold.
When they have that listed , it is for certain the special color was Tiger Gold.

I'm not too sure "O" in EO stands for 2-tone paint.
That doesn't quite jive right overall.
Possibly it is just the Fisher code that makes provisions for the molding group that divides a vinyl top or 2-tone paint scheme.

Im thinking the second 2 in 2-2 trim code is for black vinyl top.
It would be extremely ultra unusual to have a 2-tone with 2 different special order colors.
Don't think that would fly with the zone order proof readers.

Seymore might can scour his original 65 PMD build sheet and see if any of the numeric box groups list a code for 2-tone or vinyl top.
And we can decode your PHS document to see if it has one of those.
