I'll second Protech and as stated above rose joints on the bottom end of the rear shocks are the way to go. I fitted a set on my LA car earier this year along with new springs; 250 lb on the front and 125 lb on the back. Its worth getting hold of some corner weight scales (or be a cheapskate like I did with 4 sets of bathroom scales) and doing a bit of research on how to do a DIY corner weight set up - the springs, shocks (and bathroom scales!) completely transformed the handling of my car for less than £600 all in.
