Thanks to 67Dart273 and also input from the Electrical and Ignition Forum, I successfully converted my ammeter on my 66 Cuda to a voltmeter in about 3 hours. I used the guts from a Sunpro 8215 Voltmeter and mated it to the face of the original ammeter. It took a little time, but mostly just a lot of patience (especially when transplanting the Mopar needle). With a drill press and a few other bench tools, I would have made it look a bit more professional. However, all of the ugly part will be hidden by the dash bezel. The white dots indicate the 12V and 14V position on the Sunpro face, but this is not needed (I discovered later - see "patience") due to a potentiometer on the Sunpro that allows for precision adjustment of the needle position.
Anyway, this allows me a lot a latitude to put in a larger alternator for accessories.
Thanks again to FABO for putting all this info in one place.
