not sure which is best I have chased several dead ends as far as people told me they had one in an older truck but they turn out to be truck rearends not a dana 60
I have sum good friends whom helped me weld up a Dana60 from a ford pu sittin in a field for 100 and a junk yard had some ford 9 inch housings with brakes that was damaged for 50.Friends welded it up with the 9in ends and we drilled the drums to fit my bolt pattern,called Moser for the guts.I found 2 sets of gears unused for 100.I got lucky!here is a pic.35 spline since 1996 no problems millions mid 5's runs
