I am the owner of a 1973 Dart Sport 340.My hood has no scoop no holes.I have a spare hood which I am mounting the factory snorkle hood scoop.I will be opening up the hood for air induction.I was lucky to pick up the factory scoop at Moparfest this past summer($250.00)I sent the Year-one scoop back that I purchased.The fit was terrible and was made for 71-72 Demon-Dart.Thanks for info. and measurements it will be helpful.
