Is it a full width 44?
It all depends on what you want to do with the rig....how big of tires do you plan on running, do you want the tires to be hung out there?
I prefer Toyota axles, the parts for them are quite a bit cheaper, and easy to come by.
If you got the D44's already, your good to go man. Is your front a high pinion? What gearing does it have? Any clue on the width?
