Whoops, my bad, I forgot the Duster has a uni-body. Sounds like swapping out for coils and wishbone is not worth it. I was really hoping to put in an anti-sway bar as I recall it leans into the turns pretty good. I will get some pictures of the rust and get your opinions. Thanks for the good info so far.

And yes I don't have a clue what I am doing, that is why I am here asking questions, gathering information, and building a plan. I have no intention of doing anything to this car until I am well informed and ready.
