suspension setup?

I don't do a lot with the first gen cars so I think David Pozzi can help you better with set up on them but IMO the Hotchkis set up would work well for you, as for poly bushings don't use them you would be better off with stock replacement rubber (the only thing poly is good for is in non moving locations such as body mounts) or if funds allow use the Global West del-a-lums in the control arms and don't use them in the leaf springs, KYB shocks are junk get Konis, Bilstein or Edelbrocks
