70-76 Demon,Dart sport,Duster Pictorial History

Here's what I find curious: 7Demon2 has pointed out (and I believe he is correct) that the holes were originally planned for some kind of fresh air package that never made it to production for the 71 model. I can see where the factory might have left the holes in 71 if it were too late, or too expense, to eliminate them for the 71 production run. But it makes no sense to also include the holes in 72 and 73 when there was plenty of time to get rid of them. I just can't see the factory purposely installing holes in the hood if there were no plans to hook them up and make them functional. The holes have virtually no performance benefit with the enclosed 72 and 73 air cleaner. So, I find it hard to believe that Chrysler would have continued to offer an aborted, half-completed fresh air package for two additional years...especially when they would have had to move the holes from the 71 location to the 72 location to accommodate the new snorkel hood.
