Interesting - trying to do the same thing with a little different approach. Here's some vector art for the gauge faces to fit in the AD gauge. My plan is to find some plastic sign-making laminate that is a combination of black and translucent and have the numbers lasered in the black to reveal the translucent material behind so I can back-light the gauge. This image would be a negative of the actual gauge face.
The window in the speedometer will line up with the Speedhut programmable speedo. I had them add a remote reset button for the trip odometer so I don't have to drill a hole through the glass. I called Speedhut and they told me I could remove the needles from their gauges and how to reset them to zero when I reinstalled them (after telling me it would totally void their warranty)
Happy to provide the vector file for anyone who want to experiment with gauges for their AD.
What is everybody else doing for fuel, oil temp and volts?
