front end has 35 teeth, the rear 34 teeth. moving only 1 spline 1 end makes for a giant (can't remember exactly but, it is shocking - like 3") of ride height change. need to work both ends to get the ride heights you want. read the factory method. can count splines, move bar to get new marks both ends and get durn near exactly what you want, first time.
if you don't have manual. email me and i'll fwd the appropriate info.
