Nice axles, you can put a lunch-box locker in the front end, and buy a posi-lock kit, which utilizes a cable to activate the CAD front axle.
This allows you to run a full locked front end when needed, they you just push a cable mounted somewhere in the cab to de-activate one axle, cheap air style locker, and I would add a set of Warn hubs also.
And your rear end is most likely the 30 spline axles. This is identified by bolts holding the axles in, 35 splined axles used studs and nuts.

Clean them up, put fresh axle joints in the 44 (the weak link) and run them.
