It looks like a posi to me. I think I see a spring in there.

Yeah, I think those springs have something to do with the posi clutches in there.

Posi...or not???
Yes that is definately a limited-slip/posi carrier. However, does it work??
If it's still on the vehicle, put trans in neutral, block front wheels, disengage parking brake, jack one rear tire off the ground and see if you can spin the tire that is in the air. If tire spins, posi unit needs work. if tire dosen't want to move, looks like your posi-unit works!! Good luck, rwgregory

Well, you probably can't apply as much torque to the wheel as your engine can. Unless you transplanted a Honda into there. But, if it did spin you would have known for sure that it was toast.
