Racing HUD

We're going to design a specific HUD for our vehicle. My car is a 1970 Ford Mustang Mach 1, so they have a particular style. I'm probably going to try and replicate that.
Here are some photos of the style of that age.

I like the interesting colors on this one pictured above. Having the second tone to delineate mega-fast speeds is an interesting idea. 

Including details like mileage, fuel or RPM might be fun, even if I'm just going to have to fake it somehow. On the other hand, it may just confuse the player.

This is a nice and simple design. The shape of the pointy-dial thing is an important detail. The font is also very specific.
