Headliner questions for a 72 Scamp

Trying to get a headliner in my sons '72 Scamp.The car didn't come wit headliner bows , so, we found someone local that had a set from a '70 Dart and, figuring that the roof is the same, bought them. Well they don't fit the holes where they should go. We took a look at my '68 Dart and that car has clips that the bows sit in . The Scamp has no slots cut for the clips to sit in. Instead, it has 3 holes in each spot that a bow should be.My question is, do these cars take different bows or are there different style clips that the bows sit in. We have look around for bows and clips and it seems that when they list these parts, they claim they fit Dart and Scamp '67- 72, which is wrong. Has anybody dealt with this issue before to help us out. Also , is there a separate sail panel that goes under the headliner ,or does the fabric just cover the metal on the pillars? Thanks for any help you can give us.I've posted a rew pics to show where we are talking about. The first 3 pics are of the Scamp.The rest are the '68 Dart.
