I have a 72 duster 340 auto. The torsion bars are completely shot. Have adjusted them and they just keep settling out. Anyway it was a 318 car to begin with so has smaller bars than stock 340 car I believe. I am going to be replacing the drums and putting a disc conversion on with tubular upper control arms. and all other bushings needed. My question is how big of a bar do I need. I wont be doing any racing just street pounding and some curvy back roads. Also should I install sway bars? thanks
