My wife got me a set of dolphin gauges along with the dash insert for christmas last year. The gauges have the white background and should match nicely - but I still think I'd like the factory look better.

I'm also not sure if a tachometer came with that 63 instrument panel I saw with gauges. That was about 8 months ago and I just paid enough attention to know that it had a temp gauge, an oil pressure gauge, a fuel gauge and an ammeter. A tach is what I really want and I don't want anything sitting on or below the dash. That's why I might end up using these dolphin gauges. Until then, I will continue to hunt for a factory panel with a tach.
