I have two sets of reese part # 50082 custom rail brackets. One set was installed on my truck" F350 short box diesel 2011". Story goes like this: I bought the 11 in Sept. Ordered brackets presuming it was a quick install. I had to drill a few holes to acccess the def pump should it have to be serviced. Reese was unaware of the holes that were needed at the time of purchase. I worked with them drilled the holes and finished the install. Then...I received another set of the same brackets with the new holes punched in them. I didn't install them. A few months after that I received a redesigned set of which I removed the first set and installed that set. So.... I have these two identical bracket sets to give away. I have no use for them. I just ask you to pay the shipping costs. If your interested send me a message. Check reeseprod.com to see if these will fit on your truck.
