vIdentifying a Dana 44 is a little more difficult. The best identifying marks are the ring-gear bulge to the left of the center of the cover and the fill plug (some didn't have this) to the right of the bulge. Many of the Danas also had their model number cast in one of the webs of the centersection. For example, if you have a Dana 44, the number "44" may be cast somewhere on one of the webs. Not all of them, however, had this mark.
