everyone is going fimer than stock torsion bars nowdays, like 1.04's and quality shocks. Front suspension probably need the usual suspects, ball joints, ends and idler arm. What rear end do you have? A 2.76 rear with a single plane isnt going to make for a quick ride. 273 likes to rev so you need some gear under there, I like 3.55's Rust is common, just have to deal with it as it comes. They like to rust at base of rear window and front window corners. Adjust Lokar kickdown per manufactures instructions.
