Boy Lee, not trying to be an arse, but this isn't your day. The part he needs runs the full lenght of the window attached to the door panel. Normally referred to as the inner fuzzy. Little different texture than the outer fuzzie, which also runs the full length of the window but attaches to the door frame.

As noted above, even an NOS set may have become very hard if not stored in a climate controlled environment.
The door adjuster ALSO has a fuzzy piece on it. That fuzzy piece is in the link you posted There are (I think) two to each front window. They attach to the door and allow adjustment of the angle of the window. That fuzzy pieces is only about an inch and a half on each adjuster.
