Custom Gauge Ideas, something stealthy? Options

[Britain Smith]

I have gotten pretty far in the wiring of the car and I am now at the point of figuring out which wires I need to run for the gauges. Yes, I know this is a 912 but since it will have a type-4 engine I need a CHT gauge. I have the combo oil temp/pressure gauge as you can see in the picture. I also have a boost gauge for the turbo side of things. I was thinking of dumping the oil level indicator in the far left gauge since I am not running a dry sump and therefore do not have a external oil tank. Does anyone know if there is a CHT gauge that I can get custom fit in there by Palo Alto Speedo?

I also have another tach that is the 930 style with the boost gauge in it, I could have them redo that for another gauge also. I wonder if it would be possible to integrate a air/fuel ratio gauge in there? I have seen people put volt meters in there, do you think that a volt meter is necessary? Share you ideas and show me what you got...

Here are some gauges off Palo Alto Speedometer and Hollywood Speedo sites:
