A system for securing a graft within a bone includes a tubular cross pin having an interior surface bounding a passageway extending between a proximal end and an opposing distal end, the distal end terminating at a distal end face. A guide pin has an exterior surface extending between a proximal end and an opposing distal end, the exterior surface including an outwardly projecting shoulder. The guide pin is removably received within the passageway of the cross pin such that the distal end face of the cross pin biases against the shoulder and a proximal portion of the guide pin freely projects beyond the proximal end of the cross pin.
