What other details would help? Stock suspension, in good condition but has old shocks up front and sir shocks out back, so anything is likely an improvement. MY car but has been passed on to my oldest son, he got squirrelley accelerating, hit a sign, and now it is in the body shop getting fixed and that ate up a lot of $$. It does tend to sway on hard acceleration, especially if you over correct steering. So I think a sway bar and new shocks should help. 383 4 speed, has aluminum heads etc, not the fastest in the world, but respectable, I realize some supsension updates would benefit, and they may come but not at the moment. I would like to buy one swaybar set up and be done, that will work with future suspension upgrades, so if not Firm Feel then what. My thout was Shocks I can easily upgrade later?

thought the Koni shocks weren't a bolt on in the rear?
