Reducing body roll. SS springs, sway bar, or both?

I have a 69 B'cuda w/a BB and 4 spd. I run .990 bars, frame connectors, SS springs(frt hangers flipped) and Hellwig bars (frt and rear) 255/15 rear and 225/15 frt. Tires clear fine and the car drives/handles fantastic. Try the Hellwig bars.....excellent company with fantastic customer support!
