All toyota factory locker housings are notched for the actuator fork. The cable lockers are the same housing, the only difference bein the actuating mechanism is cable vs. electric motor.
ummm, someone correct me if i am wrong but the CABLE locker housings where notched for the actuator but the elec housings are not...
at least that is what i came to beleive when i installed an elocker into a standard housing..
