If you wanna get a lsd of any description you need an entire t series rear end to go into your sprinter. Do a search on here, your likely to find them in t 18 which are rear now days or you could get them out of a te27 or old skool L2000 celica however with some of these rear ends you might need someone with a jig to cut and weld all your spring perches, swaybar mounts and trailing arms.
