I know this is an old thread, but these are being reproduced now. They are currently unavailable because of supply issues (like everything else).
Offered in both gloss black and flat black treatments.
Classic Industries has them listed at $278.99 each.
Not all hoods that came with factory dual scoops had the holes cut out.
This particular hood (purple), I believe the scoops were added. All the scoop mounting stud holes are right where they should be (it's not really hard).
