Not sure how common the d44 8 lug front is, it only came in v8 reg cab 3/4's with the low gvw between 94-97 from what I have gathered, I know we have had 5 ram 2500's between 94-02 and they were all d60 including a 99 reg cab v8 truck. Safe bet is always to check the diff in person but I think its safe to say all the diesel/v10 trucks had d60 from factory but then there is always the 1 where to PO swapped it out not knowing difference.Umm…Do you know which front axle this 3/4 ton rolling chassis came with? Many 3/4 tons use the HD version of the Dana 44 (an axle you already have) The Dana 44HD only differs from the 1/2 ton D44 by having slightly larger diameter brake rotors and three more lugs. Some say the tubes might by thicker, but all internal parts are still standard Dana 44. There were a few 3/4 ton chassis that came with D60 front axles, mostly those that were equipped with either the Cummins or V10. Which did you get?
On the CAD axle thing I have seen a 01 without cad and my dad had a 02 without but I do understand it is something where it isnt a 100% shot either way but they are out there. The spool and posi lock cable thing works like a poor mans arb but you have to be on pretty much 0 load to get it to unlock, adding the locking hubs would be a great setup as you could lock the hubs and pull transfer into 4x like normal and know the power is going to driver side tire, then if you need it pull the cable for locker action. (maybe poor mans OX locker would be better comparison)
