I am not so sure you can. The only place you will run into trouble is where the center idler wheel/ rear arm shock pivot mounts. The 09 rails are pretty swiss cheesy, so there may not be room for the mount holes. The rear sissor mounts in the same location to the rails on all years as does the front shock lower shaft. Also the front arm is the same as a holz bracket on 05/06. I would get 07 rails to be sure. Or do the entire 09 skid setup (it's a lot better than 05).
