I have the Dodge add on mudflaps. They look nice but dont do a d**m thing as far as blocking rocks. I had a set custom made last week. Didnt want the 5er to look like my TT did. The flaps use the hitch bar for mounting. Slide them in each side of the tube and tighten a set screw. I agree that Jason at NW Custom makes an excellent product.
