the company that makes those and sells them to Quadratec is in RI.
www.AutoRust.comWe offer a few pieces if you're in need, but not as many as they do. We sell the transmission support skid plate, rear upper shock mounts, spring & shackle mounts for the YJ frame, and soon the rear cross member. Their rails are a pretty decent deal. My buddy bought them from there and had South Shore Automotive in Plymouth, MA do the install. If I needed that done, I'd go there or to Elias4wd.
