Yachtsmanbill took his ball and went home a few days after you joined here. You may not get a response.
Here is what I did for gauges - kind of a Day 2 look. I started with old-school SW (voltmeter, oil pressure, water temp, and oil temp), but then I added fuel pressure and air/fuel ratio in the consolette. SW does not make an air/fuel ratio, so I switched the fuel pressure gauge to AutoMeter to match the air/fuel ratio. I also got an old Pontiac vacuum gauge, and put its internals into the Buick Tachometer cup. So I have SW 0-16 psi fuel pressure gauge, if you need it.
