The factory installed an anti-squeak material that appears to be the same anti-squeak material used on the small panels screwed on to firewall near the top of the inner fender. It was stapled into place before they welded on the outer side cowl (I'm guessing). You can feel it if from the inside if you reach up high above the louvered potion of the outer cowl. I don't understand what its purpose was, as I didn't notice where it contacts anything. I would say to turn up the radio if you have one, but then its hard to hear the engine rpm to know when to shift.
