Mjhcobra,
They make a replacement Volt Meter that matches the original AMP Meter for the Smiths Gauges. It blends right in seamlessly. I have a few complete sets of extra gauges at the house but no Volt Meters or I would attach a photo. Here is one source to purchase one, you have many supplier choices.

If properly installed, the AMP meter will serve you well. Both gauge types have their pros and cons. A properly installed master fuse, CB or fusible link will protect your electrical system. From what I have seen, your choice in the style of crimped wire end connectors will be the weakest point of any non-factory wiring installation. If you use those wire end connectors with the blue, red or yellow plastic tips over the crimps that are commonly available, even with the proper tool, they have often been the source of many problems. Why? You can’t SEE the final crimp…And the colored plastic ends are more wire gauge indicators then replacements for stiff heat shrink tubing. The more expensive crimp on wire connectors require a special tool to properly install. Usually $50 to $150 just for the crimping tool. But they have two sets of fingers, one that attaches to the wire making the circuit and the other set of fingers wrapping around the wire insulation. Add to that a heavy gauge heat shrink tubing and we’re talking “Space Shuttle” quality connectors.
