Dual Scoops with Standard Grille?

Trying to find an answer but not having any luck.

For a 1972 plymouth duster was it possible to get the dual scoops with a standard grille? From everything I can find the dual scoops came on the 340 or duster twister cars and both of those had the shark-tooth grille.

Could the car be ordered with dual scoops and a standard grille? If so would you need the v8 or could a slant six get them. Thanks!!
