I'd take the ammeter out and send it to one of the companies that does gauge restoration and refacing. They can update it to a voltmeter. Don
Thank you
I called The Speedometer Shop in Riverside California.
Waiting for a call back on if they do individual volt meter upgrades.
The guy I spoke with made it sound like I would have to buy a whole set to get the volt meter.
I'll call the eastcoast shops tomorrow.
I found a meter off the shelf but its too deep
and had to make a non metalic face, the metal one would not work.
...pic.. ...pic... If the shop upgrade is not affordable I'll still try to fit something in the cluster.
