I bought mine from Amazon.com They were Curt custom frame brackets, and Curt bed rails. I think I got both for 196.00 delivered. I installed a B&W Patriot hitch on the Standard Curt bed rails. I installed with the help of another person. It makes it much easier with the extra set of hands. Everything fit perfect. Your Reese hitch will fit into the standard bed rails. Just make sure that the frame brackets are for your truck. I like the custom frame rails in stead of the univercal frame bracket kits. Only had to drill 2 holes in truck frame. The rest of the hole were already in the frame. Nice beefy brackets.
