Have any of you replace the window felt inside the tailgate? I am going to replace my motor and cable back there and when I reached my hand down in bottom of the tailgate, I got a handful of old, crusty felt that had fallen off. I ran my hand along the side of it and it just comes right off. My window strains in certain spots, when the motor was working, and the reason is probably because of the rotting felt gettin it all jammed up. So if anyone has done this, how did you do it, was it a PITA, and where did you get it from. Thanks!
