rallye gauge diameter

[buckshotbishop]

im designing a rallye style gauge cluster for my 69 valiant. if some one could get me the diameter of the gauges it would be a big help.

thanks

if im successful in my design ill be willing to make extra but they probably wont be cheep but it depends on the cost of waterjet cutting.

anyone? the standard barracuda gauge sizes would also work.
