The best Dana 60s are going to be from 78-79 or 85-91 F-250. These are HP, driver side drop, and have king pins.
You could get a D60 from a Dodge that is driver side drop, but those will be LP and have ball joints with the 94-01 have CAD.
Chevys also have D60s with king pins but those are LP and passenger side drop. So unless you go with a passenger side output transfer case like a D300, those aren't that desirable.
Only thing to watch out for is that the 85-91 F-250s also came with D50s which are D60 housings but with D44 R&P.
