The '79 1-ton should have had a Dana60/GM 14-bolt in it.

A '79 3/4-ton should have had a GM Corporate 10-bolt in the front, 14-bolt FF rear.

By 1979 GM had totally quit using the Dana44 front.

Can you post pics?

Nope. I've got the axels all tore down for a rebuild. I'm guessing you saw the lug nuts!! Haha

if its in the vehicle, off the ground and the d/line is connected, you can spin one drum/tire and the other tire will spin - in the same direction it has a locking device: LSD or locker - in the opposite direction an open differential.  note: a bad LSD will act like an open diff as well.

if its out of the vehicle you may need to unbolt the cover.

here's a good read for you...
