70-76 Demon,Dart sport,Duster Pictorial History

I have only one question: how do we know the two different part numbers don't just reference two different available hood configurations: 1) hood with scoop, and 2) hood without scoop. Again, where is the verification that the "hood with scoop" included the fresh air holes at all? Other vehicles mentioned in this guide that did, indeed, have functional fresh air packages mention "fresh air" specifically. There is no such mention in the section about Demon/Dart hoods.
