Here is a pretty cool sway bar based off a torsion bar. There are several ways to mount this system. You can also order it with Longer Rods if you need them longer.
I am probably going to try this one out with longer rods and make it a bolt on to my housing somehow without grinding/chipping the powder coat. Pretty sure it can be done with me fabbing up some brackets that bolt to the extra holes I have in the shock bracket tabs.
There are a bunch of different mounting pictures here......
