ok, so i found a good deal on an arb for a dana 30, what is the quickest way for me to make sure it will fit? Its out of a 2000 tj that had 3.73s and i have a 99xj with 3.55s? will it work in my carrier? i figure i will have to change gears, but needed to do that anyway. I know that my dana 30 is an hp and 2000 and up everything is a lp, will that matter? thx in advance
