I just had Custom gauges and a tach made by SpeedHut.com. for my 57' BelAir. They can make you a 6 cylinder 4000 RPM tach if you want. Everything is now 8K and I only wanted a 6K tach and they did it for me. Custom lighting, colors, faces, mounting options and memory too.
It was not as expensive as you probably are thinking. My tach, oil, temp and pressure gauges were about $450 which com[pares favorably with AutoGauge and others.
