this thread will help answer some common questions reguarding this dual scoop. this is a factory scoop. the measurements are taken from my car. it is a factory scoop installed by ma mopar. first the pictures of what scoop we are talking about....these scoops came on 1972 demons and 73 dart sports only! many people man say differently about their car, but these factory installed scoops were never available for the duster or 74, 75, or 76 dart sport. if it has one, it then it was added later plain and simple. remember these cars were being sold as economy cars so chrysler was toneing down the performance image....
