A rear sway bar will be more effective at controlling engine torque than the 6 /7 leaf setup in my experiance . I found some clean 6 leaf units from station wagon for my super bee , put poly bushings in them and HD shackles from Magnum HP , oh ya and fliped the front hanger to lower some cause it looked like a stinkbug ,and a 3/4 rear sway bar and the car rocks now .Poly in the spring eye works very well ,helps steering precision drasticly .The car will not botom out and hooks nicley , KYB shocks for now . I chose to use the .96 T bars and thats firm enough for me with poly strut rod bushings and tubular upper arms ,4* castor and .5 camber .I want to have firmfeel do up my K frame next .
