Hey John man! Welcome to the forums. I too am looking at doing the white face guages. When you do this you should also look to replace your guage lights with the led style. a lot of guys do different color and I plan to do the blue led's for the guages along with the white face. Here's you a link for the white face... they also have it for the heater control/hvac areas.
