the australian gazelle is drum brakes,there were disc braked diffs in japan,with lsd's,but the supply of these has long dried up.any s12 gazelle diff will work.as for a replacement axle to get you going,maybe someone in the club has a spare,as i think there is nothing else that will be the same length with the same splines,stanza,180b wagon,c22 are all longer.standard axle 1200 are all too small in the spline.aint one-off parts a joy.
