The hydro units are the same in all of them except. First it being ported or not, and even the ported "plugged" ones can be converted to a full ported pump.
And that the "super " pumps have a spline input shaft, and a different tooth count on the output shaft. The output shaft of the super will only mesh with the reduction gear from a super and the same goes for the "regular" non super pumps. The reduction gear has a splined hole in it that will fit any pinion shaft. The only difference in pinion shafts is whether they are straight cut or angle cut. This also will play a part in what ring gear, carrier , and axles you use.
