HI where is the crack/damage to the diff case that you had to change it? and the replacement is a 3.2 case, your original looks like a modified SC as for the bearing the 55mm is 930 302 391 00 and the 62mm is 999 110 032 00 both could be fitted to that year, do not forget you will need a full diff set on a case change , is the pinion bearing tight in the diff case or that loose that it takes no effort to get out??? check the size in the case as it may have gone egg shaped.
