this is one of those red steering column locking devises that go around the steering column like a clam shell with a lock to lock it closed so you cant get a key into the ign and steal the car.Was made for 84-87 GN. I`ve seen em on E-bay latley,going for $60-$80---I`ll sell this one for $40 plus shipping.It`s new in box,I never used it cause I have a theft deterant chip in my ECM-----let me know,,,Jack
