What kind of locker or LSD is this?

[toddzrunner]

I scored this locker in the pic. from my friend. He got it off his friend who managed to snap all the bolts when it was in his front end. He says its because the bolts were to short. Anyways i just got a 1987 22re 5 speed stock gears 4runner. Wondering what else i need to get this thing in the rear by summer time. Any help?

I've never seen one up close and personal, but that almost looks like a detroit.

Detroit locker image search.

I believe that is a KAAZ LSD.
