HI I AM WANDERING IF ANYBODY HAS EVER SEEN OR USED A UFO BRAKE COOLING DUCT ON A 2005 FE 550? I HAVE JUST BOUGHT 1 & I AM WANDERING HOW U FIT IT? THERE ARE TWO BOLTS,1 THAT REPLACES A BOLT IN THE FORK GUARD ? 1 THAT REPLACES 1 OF THE 2 ON THE AXLE KNUCKLE THINGIE? LOL! I CAN FIT BOTH OF THESE BOLTS BUT THERE IS A NYLON LOCKING NUT WITH THE BOLT FOR THE KNUCKLE (SUPPLIED WITH DUCT) I CANT GET THIS ON (NOT MUCH ROOM INSIDE DUCT)! WILL IT ACTUALLY NEED THE LOCKING NUT? THE ORIGINAL BOLT IS SHORTER BUT JUST SCREWS STRAIGHT THROUGH THE KNUCKLE!
