side glass anti rattle filler

Morning Gents.......Going to remove the side windows on a 1970 Dart. The previous owner secured the anti rattle material to the side glass so it goes up and down with the window. Is this correct? Was the original not secured in the front track and the window ran up and down in the anti rattle material? I am talking about the track that the vent window is in front.
The passenger window is so tight that it takes 2 men and a boy to operate.
Thanks for any assistance appreciate
