Has anyone done a custom install of the 12.3" Holley or other brand gauge displays in an S197? More specifically 05-09 but would love to see any examples. I know with the Holley unit you can customize your gauges and graphics so I think you could somewhat closely emulate the GT500 gauges. I also have had the idea of getting Speedhut to make a speedometer and tachometer to match the factory GT500 gauges and then run a smaller display in another spot. They come apart easy and I think you could fabricate something that looked pretty factory. Either one would take some modifying of a factory cluster housing to make work. I just don't want to end up with the look of a LCD screen mounted in front of my factory dash.
