Hi Pedro
The part number you are inquiring about EAT912A585 Detroit TrueTrac is only for the Dana 30 Front axle and will NOT fit your 1989 Toyota FJ62 Landcruiser Detroit does not make a TrueTrac for the Toyota 9.5" axles. If you are looking for a limited Slip then the Auburn http://jo.my/vr024r is your only option at this time other than a selectable like The ARB's http://jo.my/kxgzmg Thank You
