Dana 60 Strange Axles??

[workinprogress67]

i recently purchased a dana 60, that came factory in these trucks, for my 67 half ton. the front has been changed to a 5x4.75 pattern for a more popular wheel choice and the plan is to buy 3.54 gears, c clip eliminators, it has a posi, and strange axles with the gm car pattern. now what my dad is telling me is the guy at strange has no clue of what hes talking about. hes never heard of a dana in these trucks and actually gave my dad a number to another company bc he didnt want to deal with it. he asked all the measurements which where then provided and if the rear had gm or chrysler gears... but its a dana rear. he said they dont make sense and insist on another company. YOUR STANGE AXLES isnt a dana 60 a dana 60?? please help me out here
