OK, have yet to post pictures of my Pontiac up yet, but I need some help locating some replacement pieces. Particularly I am working on the windows right now, just the doors and side windows in the sedan, an I have these old worn out window channels/Fuzz. I have a found a few places online, thanks to the links here that sell some replacements, but I am mostly curious about what it actually is and what I should replace it with.
