70-76 Demon,Dart sport,Duster Pictorial History

But was it an OEM replacement part number or an aftermarket/Mopar Performance/Direct Connection #?

There hasn't been any proof of a Duster scoop or Duster hoods with holes listed in OEM replacement parts books, or a fender tag with any code that would indicate that scoop option.

Not sure if the Demon and Dart Sport take different numbers. Those hoods had different contours and one may fit the Duster hood better than the other.
