Weatherstrip for Sedan Windows

I have a 1974 Dart 4 door sedan.

The rubber material (U-shaped) that seals the front, rear and top edge of the front door glass has gotten hard and I'm getting a lot of wind leakage in several places.

Not sure if replacement material is available, or even how mine is attached. It looks like there is one piece in the divider between main window and the vent window, a second piece that goes along the top and rear of the window openning, and a third piece that goes in the rear channel inside the door. Parts 2 & 3 may simply be 1 long piece that is broken on mine?

The 3rd piece simply pulls out of the metal channel but the other two seem to be very firmly in place. Are these supposed to come out, and mine are just too brittle to remove without breaking, or are they cemented in, or an integral part of the metal channel.

Any sources for replacements?

Thanks,
Dan
