Well, I'm thoroughly confused now.

Do we really think these sway bars are the "good alloy steel" Bob
mentions below, or are they more likely whatevery Dodge could scrape up
and shape?

Are *both* my front and rear sway bars ('03 QC 4x4, tire & handling
package) hollow? If so, will I see a real benefit from swapping these
swaybars with the solid ones? If I had to pick one to swap, which would
be better? Is it a direct fit to bolt a '99 front or rear swaybar onto
this truck? While I have it all apart, does anyone make a polyurethane
bushing kit for these bars so I can solidify things once and for all?

If it's worth it, this sounds like a great mod to do in an afternoon
along with a shock replacement.
