New Instrument Voltage Regulator (IVR) Idea

None of those work as a drop in for a rally dash. You are pretty much stuck with improvising there anyway
Agreed about the rally dash. But they have instructions on how to do it with one of their IVRs

The back of at least the non ralley gauges had two adjustments to move the needle.

I played a bit but did not try to make one accurite with power and resisters applied yet.

One seems to adjust the low setting and the other I suspect the upper setting.

Note the teeth on the silver arms, one at 10:00 and the other at 5:00
