The two red arrows point to those awful plastic trim screws. Just pry them out and buy some new ones. They won't unscrew...at least not for me. UPDATE: 3k miles...still haven't reinstalled it. Not having it does allow the lower mouth to flex at somewhere over 125mph... But I'm going RBII nose, so I'm not putting it back in. Oh yeah, those speeds are only on a private, test track! ;-P
