Dart to Duster style door glass?

OK First lets draw a solid line between Duster/Dart Sport and Dart/Valiant Scamp. You can't cross that line. Glasses, regulaters, everything is different. I dont think there ever was a Duster or Dart Sport with vent windows anyway.
Now... To use the later model Dart/Valiant Scamp galsses in the earlier model car requires changing weaterstrip/seals where the glass meets the body and the regulater and tracks inside the door. I think the winder handle is in a slightly different location too. That may apply to only some earlier models but If so the door interior panel would need to be altered.
I've looked at the possibilty of deleting the vent windows of a 67 B'cuda ( using 74 Scamp donor ) and decided it was just not a good plan.
