A few confusing fender tag codes, V88, V9X - 1974 dart sport 360

So, I have a me a 74 dart sport 360 and am trying figure out what stripe(s) its supposed to have. The car is factory white EW1 with the small vinyl top V4X
It’s also equipped with a J54 Performance hood and V21 Performance hood treatment which is kinda cool

Where I get a little confused is that the fender tag says V88 and also V9X. Iv’e always assumed that V88 is stripe delete down the side but then I see V9X and am wondering isn’t this also transverse (down the length of the car) stripe

recap
EW1
V4X
J54
V21
V88
V9X

what’s the V9X?
