This overhead fiberglass gauge housing is designed to fit all busses 1955-1967. It mounts to the underside of your fresh air box, and offers a view of your three most important gauges, rear view mirror and the road in front of you - all at the same time. The wiring is hidden by routing it through the windshield center post. Your 2-1/16 inch gauges mounted in this panel are protected from outside elements that can damage electronics. Your sun visors will need to be shortened. Some assembly and labor are required. Panel is blank and gauge holes will need to be drilled. Gauges are sold separately.
