Question for those that have installed this. I am putting in the full length system #5. Whats with the rubber band thing that goes around the L pipe that goes in the fender well. I dont get the purpose of it. And then, the plate that you drill into your fender, why are the 3 screws that hold that in place in such a wierd arrangement. They are all on the top part of the plate and 2 are right above/below each other in the same spot. Is that supposed to be like that?
