The only differences from the Dana 80 hybrid used on some 2500's(manual transmissions and camper packages) and the Dana 80 hybrid used on 3500's are the outer wheel spindle, hub and brake assemblies to accommodate the duallies.
I'm not sure why there has been so much misinformation about 2nd gen axles.

It was 98 that I saw the outer wheel spindle that looked exactly like the 3500's. I assumed the 3500's were full D-80's and so was the odd ball 2500's that had the same spindles. I wondered why the D70 and D80 could hold the same lunch box lockers. So the axle shafts are actually D-70 axles, but 35 spline.
