Wasn't trying to start a war here. When pondering the usefulness of the ammeter vs. voltage gauge, seems logic points that that voltage gauge has a slight advantage, but both can serve a purpose.
My goal with the truck is to keep the gauges looking as original as possible, but still having them work for safety reasons. I bought a $25 voltage gauge from my FLAPS and took it apart in hopes I could repaint it and put it in one of my old round gauge bodies; but no dice, the new gauge parts are way too deep and it won't fit.
I'm going to contact Bob's speedometer to see what they have on the shelf that may work. Now I'm trying to figure out how to get my coolant temp gauge to work.
