I was flipping around Epray for VU meters for another project and came across these.http://www.ebay.com/itm/EVO...&hash=item27e6549601
It looks like they could display OIl, Temp, Fuel and Batt all on the center of the instrument panel for those who have GT panels and want to remove the gauge pod.
Would need a low amp 12v -5v converter and add a vara/resistor for the Battery reading because you would want it on the same display as oil.
The input range is adjustable, but by unit not by individual reading.
They appear to be the right size to fit in the area to have one on top of each other where the fuel and temp gauges are.
There are also black on white and yellow on black. The yellow on black are more.
Just thought I would put it out there.
