You are right, some sports do have the larger axles but if i remember correctly, they are not compatible with the axles found on the fullsize montero. This makes it dufficult when trying to fit a locker into the montero sports. The sports had a lot of variations during there run. The earlier sports had rear leafs and smaller engines while the later models offered rear coils and larger engines. If you are considering a sport I would look for one with the factory rear locker.
