I ran D60 rear for years. Not as tuff as a 14FF but one tuff axel!
I had aftermarket 35spline 1.5" shafts with a Dana Powr-lock posi

That posi is the closest thing to being locked with out being locked
D60 parts are more expensive than 14FF parts, for the most part. There are more aftermarket mods avail for the 14FF than a rear D60.
