Re: Axle type
There should be a metal tag bolted onto the diff cover that'll tell you. Also there should either be a 30 or 44 casted into the housing ribs. More than likely it's a 30. Also look at the knuckles. I believe the 30's used old style trunion bearings rather than the upper and lower ball joints.
