Well if I remember those slide-a-links already have solid front bushings. I would still do the rear with the del-a-lums, they are a superior bushing and will also help with lateral deflection. I'm still suprised its moving that mucy, are you sure the feeling you are getting isn't from some kind of odd slid-a-link setting? Too much preload? I would think the rear swaybar would help some, since it would resist bodyroll= less pivoting/less axle side movement

EDIT: also do you still have the rubber bushings between the axle and leaf spring. I would be getting rid of those too.
