Torsion bar upgrade

I agree with 'superdart,' about the torsion bar size. Too stiff will make it jittery over pavement imperfections (larger rims w/performance rubber and high pressure gas shocks will compound this) and the ride will suffer somewhat. My alignment/frame shop connection told me that w/the old Mopars use a stiff front anti-swaybar and a moderately sprung bar in the rear-they'll oversteer if the back is too stiff due to the semi-elliptical leaf springs (which actually turn into turns by design).
