Rounder 70

Does anyone know the best place to buy the window guide channels for the doors and qtr windows for a 74 Omega? Also I haven't been able to find the rubber wiper piece that goes along the top of the door/bottom of the window. I have been told that the guide channel from JC Whitney works but is just plain rubber and I would like to find some with the felt material on it to keep it as close to OEM as possible. Any help would be appreciated.
