Rearend modification costs?

Thanks @el5dart I did not know about Dr Diff. I just saw this a couple miles from here. Dana 60 from a truck. $100

Would that be a good place to start. Shorten to length, new perches, axles etc.

then get these .

7400 - 8 3/4" Mopar & Dana 60 Housing Ends - Moser Engineering

and these

7205 - 2 1/2" Wide Leaf Spring Mounts (Ford/Mopar type) - Moser Engineering

and then whatever axle shafts you want, moser, yukon, strange etc, some brakes from doc diff and call it a day.
