Do your Dart Sport/Duster windows seal properly?

You might have already known this, but just in case, there are adjustments for where the glass ends up on the top of the door. If you remove the door panel and then take off the plastic cover that is on top of the door you will see a couple of little metal tabs with a rubber end turned up. By loosening the bolts in these you can push them in or out and should be able to seal it up that way. I have not replaced the seals on that part of the car, so I can't really say whether you just picked up some funky weatherstripping or not. Maybe that helps?
