I meant I read something a while back about CC perches being different but I cant remember what exactly it was.

I might work if you use the K20 hangers on the C30 frame but you would have to cut and re weld the perches on the dually axle and that will put your springs closer to the tires. Ill do some measuring tomorrow to see if you could get away with it. But yes if you successfully do all that the truck should sit level.
