Heavy duty torson bars for my 1964 plymouth valiant

My 1972 Duster had slant 6 torsion bars when I got it with a 340 (iron heads) and 727 transmission. I installed PST 1.03 torsion bars and left what ever front shock that was there and am very pleased with it. I bought a sway bar and have yet to install it and am very pleased with the performance in the WV curves so far, very little body roll. Also installed power disc brakes and not nearly the nose dive as before. PST recommends their matched Billstein shocks for the 1.03 bars but I did not go that route, and have no complaints so far. Also, they are very responsive to any questions or concerns you may have, so definitely recommend.
