You are buying the oil pressure gauge kit for an SOHC 1969-1978 cb750 Honda. This kit includes a quality compact gauge with chrome bezel, billet aluminum oil galley adapter, o-ring, and the chrome 90° fitting (1/8" NPT). This it the whole kit and comes with the parts shown in the last picture. I have 4 gauge face options available: white, black, machined, and carbon fiber.
Easy to follow installation instructions are provided. Sorry, this does not fit the hondamatics. Please reach out if you need one for the Hondamatic. The 90° fittings and oil galley adapters are Made In The USA. The liquid silicone filled gauges are made by Marshall Instruments Inc.
