I replaced all mine with new springs from St. Lois Spring for the same reason as HandyAndy - the shorter leaves had worn into the longer leaves. I also got the u-bolts and nuts from them. The springs came with new bushings installed. I got the fronts one summer when visiting my folks near St.Louis and the rears the next summer. I called them with the order in the morning and picked them up that afternoon. Very good service and quality!
