LUVERNE 480743-580743 Polished Stainless Steel Side Entry Steps Truck Running Boards, Select Chevrolet Silverado, GMC Sierra 1500, 2500, 3500 HD Crew Cab Fits select: 2007 GMC NEW SIERRA

I had some issues installing the running boards on the passengers side. The center bracket was too short in length to align the running board mounting holes. I had to elongate the mounting slot in the bracket that mounts to the frame to align the running board holes. The center bracket was also too short in height, I ran out of adjustment on the center bracket and had to add a 1/4" shim. I also had to file the slots width in the rear brackets so the threaded rod would slide through. The carriage bolts that hold the running boards to the bracket seem small, I believe they're 10-24 screws. The section of the brackets where the slot are for the running boards should be longer. The washers for the running board mounting screws are about 1/4 of the way off the end of the brackets. They should also include Loc-tite thread-loc. Other than that they look good.

Need better pictorial instructions
