A lock assembly includes a lock housing with an annular wall separating an end wall and a face. A core is received in an opening disposed in the face. The core defines a keyway disposed in rotational engagement with an end portion for actuating the lock assembly between locked and unlocked positions. A drive member is rotationally interconnected with the end wall of the housing. The drive member is disposed in driven engagement with the end portion of the core. An adapter defines a generally X-shaped slot and is fixedly attached to the end portion. A tail piece is received by the slot. The tail piece defines an elongated substantially flat appendage including a proximal end retained in the adapter and a distal end extending outwardly from the adapter. The proximal end is twisted relative to the distal end between generally 40 and 50 degrees.
