Stuff wanted for gauges

[dnb]

I have decided to turn my attention to Griff instrumentation. During developing the EPAS for my car I needed to measure the accuracy of the speed sensor. It turns out that it is very accurate, but the gauge itself is shockingly bad. I have decided therefore to make some stepper motor based gauges out of the standard ones.

I would like to procure some spare aluminium surrounds, because these are easy to break and a (non functioning is fine) speedometer for experimentation.

I know I could buy stuff, but want to keep things looking original.
