Alrighty, here's the deal: I absolutely hate the gauges in my '04. They're green, they're generic, and I love giving my car a personal feeling. Enter the retro gauges found on the Bullitt and Mach 1's. Sleek, different, and exactly what I want. The one question that I have (and unfortunately think I know the answer to) is this: what about speedo calibration? I understand you have to change the board out and whatnot, but since the speedo goes higher . . the numbers are placed closer together, right? Meaning the speed registered is going to be totally whack. Someone please correct me if I'm wrong; I'd love suggestions if anyone has any ideas on how to accomplish the look without the technical snafus.
