sorry, I had foot surgery 2 days ago and I'm on pain pills
the munting holes for the front s30 sway bars on the frame rails are closer together than most aftermarket sway bar mount holes, the larger aftermarket bars use a offset plate, basicall a 3/16 plate steel that has a set of holes to allow you to bolt the plates to the factory bolt holes in the rails, then an offset pair of holes to allow you to use standard aftermarket sway bar mounts backed with nuts to the inside of the rails
the rear mounted rear bar risers are an aftermarket piece and might have larger bolt spacing or might require a similar solution, the only factory s30 rear bars mounted forward and use a unique pocket/bushing combo
