I installed new run channel kits on my 48. Passenger side works real good but my driver side is tight and rolling the window up and down is very difficult. I actually broke the crank on my regulator. I played with the guide that bolts inside door and checked it out. I made sure it was straight and reinstalled. I can tell it is still a bit tight bc moving the window up and down when not connected to any thing is still a bit tight.

Kind of gave up in disgust and figured I would reach out to some fellow bolters...
