Know the code for option?
Don't take my decoding as gospel until you've verified it by looking at the back side of the tag. Anything with a question mark or other notation is quite possibly wrong.
I don't care for the current scoop a'tall. In my opinion, it's too blocky for the car's swoopy lines. The white finish is kind of off-putting, too. If you keep it, I'd suggest painting it to match the body. Scoops don't need to be a different color; they stand out just fine by their presence. That's my take on it; opinions are plentiful and varying.
However, if you
want a scoop other than what's already there, I'd suggest the "original" scoop used on Dart Sports, as very-well photographed
here. It's a great-looking scoop and factory to boot (probably not by '75, though). OER reproduces it, but I can't speak of the quality. Perhaps others can chime in on that. I know this much: Avoid the one made by Showcars in Canada. I've yet to hear anything positive regarding their parts.
Those were always black as far as I'm aware, which might clash a bit with all the white on the car once you've reinstalled the vinyl and over-the-roof stripe. Try it black and see if you like it. If you don't, paint it body color:
