Bentparts is right. Sorry for confusing abbreviations. Mine is a converted Samurai rear diff, which has the higher spline count of the 95-99 Tracker (I find the hard way of doing things. Shop Built = homemade). The drivers side axle has the 3 bolt flange for the CV so it is fine, the passenger side axle/cv combo needs the higher spline count requiring the 95-99 CV's. If you measure from the axle housing on PS to the axle flange on DS, and it is same as your tracker, it should fit with the 95-99 CV on Passenger Side. 99+ they widened the vehicles and CV lengths changed.
Mounts might be different, but you should be used to that by now.
