The problem for me is the best place to put the touch screen is where the existing Gauges are. I may be able to fit the monitor, DVD drive and 3 gauges in the existing bezel by rearranging things. That still leaves me 1 gauge shy.
So I'm looking into the possibility of dash mounting at least 3 gauges. I will also start searching for whether or not someone has developed hardware and software for reading gauge inputs from an old car and displaying them on the screen. I'm not worried about speed or RPM's just Fuel, Water and oil temps, Oil pressure and Volts.
Here are 3 preliminary concepts:
I'm leaning towards #3 it's kinda old school and since I have quite a bit of burled walnut veneer in the interior I could cover the base easily.
The key to the whole thing is how well I integrate the screen and DVD into the gauge bezel.
