I'm glad you brought this to me, LM. I had no idea. I just looked at my dash -what about drilling the guage faces out and attaching a piece of sheet on the back side and using photo reduced guage faces from Best? In
That would be a good solution. In reality the gauge is 3D in that the numerals are on the lens and the lines are behind the needles which are behind the lens. This looks really cool especially when lit up. To most people it probably doesn't matter, but the only reason I'm finicky about it is I made a bedroom clock out of one from a parts car and look at it every night!
