I was thinking about this the other day, as I want to ad a sway bar to my SASed rig to help it's street (windey mountain road) manners a bit. The ideas I have come up with are:

1. If you could somehow modify the existing stock swaybar mounting, so that the sway bar could still be used. Then, you could get another, duplicate sway bar. You could cut about 2" off of each end and piggy back it on top of the mounted sway bar, and attatch it with about a dozen SS hose clamps. This would get you a much beefier set up than that of just the stock bar alone, but still be in the cheap price range.

2. Search 'Pick a Part' type wrecking yards for a sway bar off of a s-10 blazer, ford explorer, or an american or import mini van. Basically, something off of a vehicle that has about the same width as our Toys. My Mazda mini van has a way thicker bar than my rig has, and even has a rear bar, too. These junk yard bars should be $20 or less. And just fab up the mounts and disconnects.
