34 or 38k, depending on the springs used.

34, 38, and 44k all use the CRD 92 & 93 carriers.

The 34 & 38k have (8) 9/16 studs on the axle end.

The 44k has (6) 5/8 studs on the axle end.

The 55k has (8) 5/8 studs on the axle end, but that has CRD 112 & 113 carriers

The 65k has (8) studs on the axle also and has CRD95 & 96 carriers.

the 44 is cast steel ,the 38 is a welded housing!

On the early models that is true, but more recently the 44's have been available with the pressed steel welded type housing or the cast steel type housing.

The cast steel type housing is preferable because the pressed steel 44 housings are prone to cracking at the left side in the area where the diff bolts into the housing.
