1970 Valiant Duster Go wing option?

Was the rear Go Wing an option on the 1970 Valiant Duster? Or did the wing (and scoops) become options for the first time on the 71? I've always read and heard that 71 was the first year they were available.

The hoods scoops were never optional on a Duster. The scoops were part of the 1971 Duster Twister package. They were not available on Duster 340's
