Jack up one side of the rear,and mark the backing plate to the drum,and then mark the pinion to the housing,and then spin drum 2 turn's,and count how many time's the pinion turn's.for exsample if it turn's 3.5 time's to 2 full turn's=3:54's.This is for limited slip type's.Does the cover come off from the rear of rearend or does it come off from the front?probaly a 9".This i was tought in scrapyard school.(LOL)

300 I6's came with a taller gear than that.

Maybe 3.00 or 3.25's.
