The cab length steps look and work great. The driver's side went on easily. The passenger board was a different story. Unlike the driver's side the passenger side didn't have the right holes to bolt it on. I tried to find instructions online but I found none. I ended up drilling two holes in the inside of the rocker panel and used a wire to pull a 5/16 bolt through the existing holes in the bottom of the rocker panel. It worked great. Painted the area where I drilled and it is very strong
