Thats what I was thinking, the bushings are toast as well. Should I not do anything to the front end suspension? The shock absorbers seem to be fine.

Well, as Dan has already said, at this late date your suspension is likely fairly worn. I would replace the rear springs, replace the shackle and eye bushings on the rear springs, and inspect the entire front suspension. Chances are you need to replace most if not all of the front suspension bushings and ball joints. There have been some advances made in the technology used in bushing materials and other front end parts. Search the website for people's experiences using polyurethane instead of the standard rubber or high density rubber bushings.
