I have an NOS dual snorkel scoop that I bought many years ago. Finally decided to use it and put it on my 70 Dart. I started to do mock-up and set the scoop on the hood to see how it would look before drilling any holes and discovered there is about a half inch of gap where the center forward stud is. All of the perimeter holes sit flat on the hood. I then set it on my 71 Duster to see if there was any difference and while the gap decreased to maybe 1/4" there is still a gap. I heard there are 2 versions of the snorkel scoop. Would my scoop be the version for the later Dart Sports? The numbers on it are 3573698 and below it, 3672605.
