I can't help with the color question, that paint was the only part of this gauge that was not rusted. This is my 'get it on the road' solution made out of assorted used gauges, all of which had guts to deep for the AD housing - I tack welded the individual gauge bodies into holes in the housing. The face shown is just printer paper glued in place - not a long term solution. Lighting is some LEDs in center and a LED strip around perimeter, it works but I'd prefer backlit translucent gauge faces with illuminated needles.
I have a spare set of OEM clusters I want to do a nicer job with now that the truck is a driver....
fauxgt, what gauges did you start with? They fit into the housing nicely.
Does anyone have good ideas about how to backlight a setup like this with a custom gauge face overlaid onto a modern guage?
