Reproduction for the cylinder portion of the ignition lock assembly. Includes the lock cylinder and keys. GM referred to this part as a "first design" lock cylinder assembly for 1978 models due to the fact that the part does NOT have a slot for a retaining screw that later 1978 models did have, due to mid-year change.
