The overlay was purchased on ebay, it let a bit more light thru that I wanted so I used the existing gauge face as a pseudo filter. I used the smallest ball mill bit I had for my dremel and at a low speed milled off the orange from the existing face (out of the dash of course). That and some minor touch ups on the back side with black paint (just to match up with the differing fonts) and voila! New face. Well, that and 15 led's (plcc-2 style...ultra bright blue)
