Ok, heres my question, I don't have posi in the rear end of my pickup (89 S-10, 4.3L), and it's 4x4 so a complete gear swap is basically out of the question. I mainly want posi for the winter time when it is slick as scum on a louisiana swamp, and when I go off roading. I believe that the carrier is the thing that matters. So my question is where can I get a new/remanufactured one, and how much would it cost?

Thanks
