Swaybars are a good option, many hi-po mopars came with front swaybars, you can use originals or aftermarket swaybars from Addco. They are mounted to tabs on the lower control arms which can be easily welded on. Ma Also, if you do install front and rear swaybars both, be sure the front is heavier, stiffer - if the rear swaybar is stronger than the front swaybar (or worse, rear swaybar only) the car will understeer dangerously. (I know, some people will say otherwise based on autocross applications, but in that case the very stiff front springs used acts as additional front anti-sway.)
