cool, great info fellas!!! will cotinue researching. reason i was wondering about the D30 is becasue i already have a complete one in my posession out of a CJ. Figured i could keep the other parts as spares (shafts, spiders, housing if need be) versus selling it for 75 bucks or something.
am looking more into what type of MC and P-valve would be best, as well as the pirate threads. this type of research is WAY better than doing crap for school.
