I don't think I ever saw ladder bars on a big car. I believe they still make a sway bar kit and also a set/pair of solid torsion bars. Maybe Lakewood or Competition Engineering. But I would do what Sam suggessted by changing all your bushings, snubbers and what have you with the new style material they have out now. Can't think of the name of the material they use for the new suspension kits. Neopreme maybe

my spelling!
