From what I have read there is at least three different Dana 30 front axles high pinion, short low pinion, and long low pinion. I know that mine has the high pinion Dana 30. Are the master kits all the same with all three axles or are they different, and if so what is the difference? I plan on re-gearing eventually and I will need a master kit along with two extra carrier bearings and an extra inner pinion bearing so I can make setup bearings.
