Needing front sway bar info.

[rs74]

My short bed doesn't have a front sway bar on it and I think I would like to put one on. From what I gather it will may a big difference in how it handles. Since I am rebuilding the whole front steering, suspension and putting a drop kit on it I want to put this on now. Is there a certain diameter size I should be looking for. Any manufacturers making a good aftermarket sway bar. Will a factory sway bar be just as good with new bushings.
