I think I worked out how I would do it. I am going to make a custom console that resembles the 67 console in shape with some modern twists. I made a Soldworks modal to help me get everything the way I want it. The only problem is I am in Japan and my car is back home in the good old US. I will hopefully be home in a couple months so I can start building it. I would be interested in seeing some pictures also of screens in a classic mustang. the main thing I worry about is it will look to out of place.
