This five-hole elliptical gauge panel is highly polished to a show quality mirror finish. It is machined from a solid piece of 6061 aluminum and is fully ribbed for the nostalgic look. It is machined so that your gauges will be recessed into the panel and will fit Classic Instrument Gauges. Small gauge hole measures 2-1/8″ and the large gauge hole measures 3-3/8″. Gauges sold separately.
