Congrats! Setup looks to be the same as my disc brake Dana 60.

 

That's a massive chunk of iron.

 

Probably takes several hefty folks to lift it. Hope someone had a tractor with a loader on it to place that rear in the back of your truck..

 

Well we didn’t have nothing to put that in, made a makeshift hoist with logs🥴

 

The drum and disc flange is different the disc holes are narrow and wide and not symetrical like the drum. The axle itself is identical. Do you have a disc brake 2001.5-2002 dana 80? If so can you please measure the spindle where the backing plate bolts to the flange, to the end of the threads? I want to do the opposite of what you want to do disc on drum. I believe that the disc measurement is about 6-3/4 where the drum is 6-1/4. I can get you the drum length on the spindle length. I know a guy that makes flanges to adapt one to another.
I have a brand new dana 80 Dodge 94-01 rear axle with carrier and 3:55 gears.
Get back to me and let me know if you can get that distance on the spindle. Thanks

 

I misread you are trying to put discs on drum axle. Sorry.

 

Now who's confused?

 

Who's not confused about any parts swapping adventures?
