WTB-dual snorkle hood scoop duster dart sport style

Do you need one for a Dart sport as you state ? Or will one from a 72 Demon work for you. They are different where they sit on the hood . The lower front which unscrews is shaped different for either car Dart Sport or Demon. They never came on a Duster . The Dart Sport scoop fits an early Duster ,Valiant Scamp 69-71 and the Demon scoop fits the later Duster ,Valiant, Scamp 73 -76 without any mods to the scoop. I have a mint 72 with all fasteners and seals for the hood.
