Default Re: Differential help

D44 common, not unusual. GMC used D44 in those years. I think Eaton used also. You may have Eaton....or who knows. Need pics. Where is the diff drain plug? On the rear cover or the housing? "D44 or 44" is cast into the housing. Clean and inspect for all markings. Could even say "45". We are assuming 10 bolt of some sort.
