The gauges is used are AutoMeter's Phantom series. I bought the tach and speedo in 5" size. Te tach is electric but I had to go with the mechanical speedometer as I have a manual tranny. It will use the existing speedo cable.
I went with the smaller gauges in 2 5/8". I am using a quartz clock and then an electric temp guage, I believe there are only electric fuel guages so that is what mine is and then of course the voltmeter is electric. The fuel gauge can work with the stock sending unit.
The gauges are illuminated. They give two covers for the lights, can't recall what colors they are.
For the original tach hole I went with a 3 3/8" oil pressure gauage that is mechanical.
The gauges that require sending units, other than the fuel gauge, come with sending units.
The gauges come with attachment brackets that work very well if you are going to attach the guages with the bezels on the outside of your instrument panel. I'm not sure how people attach them when they install them totally behind there panel.
Here's a pic of the back side of the panel, mostly wired up.
The bezel originally had a silver/chrome ring around the sides and was black. I went ahead and went all black when I painted it. Really a pretty easy modification as long as you take it slow and don't like the grinder get away from you when enlarging the guage holes.
