I would like to put Auto Meter 2 5/8 mechanical gauges in my car with my new motor (oil press./water temp.). I was thinkin of getting the vent mounted cage with smaller vents on the side. Do these gauges come with the right sized fittings to thread into my block and lower intake? It looks like the water temp hole is pretty big and might need an adapter. Anybody have these gauges installed? Need some info, thanks guys.
