I have the stock Ford flaps on ours and would NEVER go with them again. The holes for fastening them are not drilled accurately and they are crooked (not even CLOSE to vertical on the outside edge), and don't fit consistently the same from side to side. One side covers the outside edge of the rear tires, the other one is almost an inch short of doing so........they really are just crap! They don't even fit closely to the side of the body on the outside of the truck, which is going to be a problem with dirt and rocks going in there between the flap and the body!!!
Go with Weathertech or someone else who CARES how they are molded and how they end up fitting....I hate mine so much that I am even thinking of throwing them away and going with another brand!
