I had done the Modshack Fang Air Duct modification quite awhile ago, and was reminded of that when I went to install the Stillen Brake Cooling Kit. One of the steps of the old DIY was to break off the plastic tab on the fascia so you had a flat surface to mount plastic 3 inch duct adapters. Therefore, when I went to install the Stillen bracket, there was nothing to attach it to. Luckily I had kept the plastic fang inserts, so I mounted those back on the fascia, and removed the bottom clip and moved it to the top tab upside down. Worked out pretty good.
Then I had to relocate the fang vent hosing somewhere else, so mounted some PVC gutter downspouts under the crash bar and moved those to that location. Not a great setup, but still somewhat functional.
