a full S-10 swap is too many compromises. especially running 2" spacers in front. to add a sway bar to a stock frame with my cross-member or to any vehicle, get a universal anti-roll bar kit from any of the race shops.
there is nothing that says a sway bar needs to be a funky bent piece of metal. or even that it has to be under the frame or have arms facing backwards.
a 1-1/4" diameter splined sway bar kit with adjustable links is about $200 shipped. http://www.colemanracing.com/Sway-Bar-1-14-49-Spline-Solid-P3539.aspx
use a 1" hollow kit for the rear
as for the crossmember kit, still $475 for forum members plus shipping. Still made in the USA. Still welded and fabricated by a friend of mine's shop in Wisconsin to be central for shipping
