i have a 1971 duster with a late k-frame big bolt stuff. i am adding a large sway bar from firm feel soon. already installed QA1 adjustable front shocks that are awsome! i am thinking about a set of tubular upper arms. i am building this car for hammering in the curves,auto-x,and hopefully open track days. i want something i can beat on and not worry about it! any help,comments,suggestions welcome.
