Pretty interesting
Will the volt meter your using have the same needle sweep?
Will the needle match?
Will it fit in the original housing? Or are you going to have to modify it?
I've thought about doing the same thing.
If your successful post some pics and instructions.
I would just probably still use the amp decal and just note the needle position or have someone scan the decal and change the lettering. But this project is down the road for me
I don't know a color match for Gage face, maybe someone will chime in on that
Good luck and keep us posted on your project
