I checked out the glow shift gauges web site and, no offence, but they just look generic to me. From my experience with gauges, You cant go wrong with auto meter. They cost about twice as much as most gauges, but you get what you pay for, especially these days.
No offence taken. I like the blue digital display and they dim when I turn on the headlights. But you are right. You get what you pay for. I might have to switch to Auto if the gauge size is 2 1/8. I should be able to use the wires also. Glowshift calls for 18 gauge but I used 14 gauge to help with any noise.
