I have a Dana 60 from my 1996 2500 2WD. It has no internals now as I lost a carrier bearing. I ended up buying a complete Dana 70 and out of a V10 truck in a junkyard, they seem to be MUCH easier to find then a 60. It was also a cheaper alternative then buying the bearing and new gears for the 60. The problem is the differences in the shock mounts, brakes, and lots of other changes from first gen to second gen. I have two Dana 70's for first gen trucks too.
