Thanks all. They are Husky Liners mud flaps and I got them from Summit Racing. $29.65 a pair, free and fast shipping. The front are held on with 2 factory screws that are for the fender flares. The backs use 2 factory screws and you have to drill 1 hole. I had to take the wheel off to fit the drill in there. The fronts fit perfect, but the back is off a little. The rear fender flare isn't square like the front, but the flap looks like it was made for a square one. The bottom fits good though.
