The Stovebolt Site Forums The Shop Area General Truck Talk 67-72 Gauges

I have been checking out the various gauge options for the 67-72 Chevy's.

I have only seen the gauge bezel with Amps, Eng Temp, and Eng oil pressure at the bottom of the bezel. What other gauge might have been an option for the 4th hole?

I've considered a vacuum gauge, a small tach/engine hour meter or maybe a clock? Thoughts?

I have also noticed that the Light and wiper switches are in different areas. I know that a mechanical choke is/was an option, but what other switch might be in the dash bezel (on the example the lower right hole)
