Bob,
You sent me a PM asking that I reply, but I'm not sure that I can add anything to what's been posted to date. You seem to have an idea that a swaybar from an early '90's Crown Vic or Impala might fit your application, but you mention modifying an OEM to fit. The problem with modifying an OEM is that the swaybar is a hardened, spring steel torsion bar, and most anything you do to tweak it is going to involve heating to bend it or to form new attachment points, followed by the need to re-heat treat it once you're done. It can be done, but it takes the right application of heat, soak times and then controlled cool down - I've forgotten too much of my metallurgy classes to advise you.

The easiest (not the cheapest) approach is the universal swaybar kit like the one Evolvo posted above. Other than that it is going to be a hands on search of your local pick 'n pull junk yards looking for something that fits as is, or if you can handle the heat treating, finding one that you can modify and then make good again without making it ductile. If you have new, specific questions on the swaybar that you have not asked here post them up and maybe someone can help you find answers.
