The support plate includes a plate having a centerline extending between opposite side walls of the plate. The plate includes a fastener hole for receiving a fastener to couple the plate to the pin rack system and the frame. A set screw is connected to the plate for adjusting position of the plate relative to the frame and thereby adjusting position of the pin rack system.
