Ok thanks, boatec doesn't have anything on their website about Superdutys though. Yeah I've heard that they aren't simply bolt on and I would be better off taking it to a body shop.
I'm wanting to run something other than pocket fender flares so I've been looking into Fiberworx fenders. I'm not to sure about the durability of the fiberglass fenders, does anyone have any input on this or pics
