RCCI has a great reputation for quality, service at a fair and reasonable price. While he doesn't cater to the Concours crowd, his headlight relay systems, voltmeters, and replacement dash cluster pods from indicator lamps to indicator lamps and tachs are what a lot of people want. I deal with Bob semi-regularly, and I can't say enough good things about him.
I know of a quality Ford and Shelby gauge repair guy who has a very good reputation; if you want a reference, PM me.
