Looks like 4-5"... which would make a big difference on a stubby Amigo wheelbase. If Isuzu didn't use a different number of dog teeth on slip vs fixed ( <img src="/forums/images/graemlins/rolleyes.gif" alt="" /> ), I'd just get a fixed-yolk case and swap the back end onto mine. Unfortunately, doing so would require buying a new set of Tera Lows which isn't going to happen. I need to pull the back half of my case off again sometime and see how far up the output shaft is splined. If they're far enough, one could potentially lop off a good portion of the snout and just cut down the rear output shaft to match what's needed to mate up to the married case.
