NO. The smaller one is not a posi. The posi you have, I have only seen in an Olds or Buick diff. IMO not a very good one either. The axles lock by the cones outside the side gears, instead of clutch's like a Chev. I never had good luck with the cone style holding up to much HP. The cones wore into the housing, and slipped.
