I have been needing a new speedometer for my CJ8 and found an interesting unit from SpeedHut. They have a gauge that fits right in the old speedometer spot and uses GPS for the speed. The reviews I have read are good and this would allow me to lose the speedo cable and never worry about gears and tire size. They are a bit pricey but would make for a nice unit for my latest engine/tranny/tcase swap. Have any of you used one of their GPS speedometers ?
