Thank you to all who replied,
I'm still going to try an source a 3/4 or 1 ton set of axles for my truck. That will at least give me the bigger brakes up front on the 44HD and will net me a Dana 60 rear. The larger stuff has to be at least a little more resistant to failure than my current axles, not to mention the my trucks front axle was full of mud when I got it... which gives me doubts that it will last any length of time behind any motor. In addition, my current wheels and tires are total crap so I don't mind changing bolts patterns.
I will upgrade to a Dana 60 front when I can.
Next silly question, can I build a Dana 60 front that is compatible with a full time transfer case? I know I can source a Dana 60 and simply keep the hubs locked, but did any of the later CAD trucks have Dana 60s up front?
