I have a few questions on my gauges and reducing the voltage to 6v. 1946 GMC

Do I need to reduce the voltage on the wire coming from the starter going to my my amp gauge? I don't think so, mainly because that is the primary power feed for everything else. But then will my amp gauge read correct?

I have a power wire coming off the ignition switch that goes to my temp gauge that pig tails up to my gas gauge. I was thinking I would reduce the wire coming into my temp gauge to 6v and then the loop that goes up to my gas gauge will be 6v. Anyone see a problem with that.
