While I should be finishing buying parts to turbo my 6.2 I am thinking about adding a locker to the dana 70. I did some searches and I still am unsure. Does my 82 dually have a dana 70 or a 70hd? Will it have a split carrier for the cheap detroit? Should I just finish the Turbo and leave it open for towing? Why does money always burn a hole in my pocket?
