I just recently did all of the above except tube control arms. Polyurethane bushings, new springs, all new rod ends/ball joints, pitnum/idler arms, re-man steering box, rag joint. Front disks from a '74 Nova totally bolt on ! I don't see the need for tubular a-arms unless you have to get the car as light as possible. It's going to drive better than new. Happy motoring and good luck !

Also going to a larger sway bar and gas shocks. Don't have them yet.
