Gauges Anyone used Boneyard ones?

You could make it work. Keep in mind that the newer gauges usually requires a different senders or sensors. And maybe some fabrication to make the other gauge clusters work with the dash. There is alot of folks on here who have made customized dashes, and lots of them are pretty cool. Some even built one from scratch and just put in aftermarket gauges.
Unfortunate thing is the really cool looking gauges are usually the more expensive ones.
