Do a search for member BigBob. He has a set of Xenon fender flares on his dually. From what I rememder, they are flares for a 1500. He had to make some minor modifications to the rear flares and also had to do a little fabrication of mounting brackets for them. From the pictures it was a very clean installation. When the time comes, I will be doing the same and adding a set of Putco running boards and blend the 2 together.
