hi
the 08 susp will bolt under your sled no problem as long as you use the 07 or newer rails also the challenger extreme will fit under your sled with out much mods either i run 07 susp with 07 rails and the 156 challenger

just a heads up...

I Put a CE under an 08 1000 and did not realize you need to trim down the rubber drive nubbs on the outside of the track closest to the dd. Also like every 3rd or 4th clip is a different style this will have to be ground down as well or it will wear a hole in you dd...Put a new suspension under the sled last week and pulled drive to change oil and found a wear groove in the back side of diamond drive.
