Yes, for the 9" anti-ratcheting driver, you are supossed to cut 3/16 of an inch off of them so they clear. The 8 inch should be fine. As for it not fitting, which protector is it hitting, both or just the tunnel. I went under my tunnel protector the other day with a dremel and started grinding a little off of the tunnel protectors. You might want to try that. My old track used to rub pretty good on both my front and tunnel and it got annoying so I figured I would cut a little off wear it was rubbing, fits great now, no rubbing.
