A lot of nissan guys down here have SAS'd thier trucks using waggy axles, and i've looked them over a bit. What i meant when i said the nissan kit would work was it uses the driver drop waggy axle and it has all the mounts and linkages you'd need, i didn't mean it would just slap right on. You'd likely have to make a crossmember or two but that's kid stuff.
