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

It’s a 72 Duster. Just street driving. It’s set up similar to 71GSSdemon’s above except it’s a bit higher in the front. It does hook good the way it is when I need it to. Yes the wheels are 10” and this is the only issue. Nothing inside rubs nor the right outside. I’m think a sway bar will solve this issue for the most part from what y’all are sayin.
