Could you run a wire to the negative on the amp gauge to the dash frame to ground the cluster better? Would i would like to ground mine better but I don't see anywhere to put a ground in the cluster. Other than the negative side of the amp gaugeI would add one. Not familiar with those "rigs" but the A bodies are "famous" for poor grounding, which originally was through the cluster mounting screws. Just add a piece of wire and bolt it to the dash frame or column mount
Yet again you teach me something new. Thanks del. By the time we're done I will know something about automotive electronics!NONONO!!! LOL. The ammeter is NOT grounded!!! That great big huge gigantic black wire on the ammeter runs to the alternator.
What you need is simply look at the cluster. Look at stuff like the illumination lamps, and the board traces. These are all connected together. One trace is the ground side, and works around at some point to mounting screws on the cluster. Any one of those is a ground point and you can use one of the screws.
Since there are several cluster designs this is difficult to show. This is out of a Dart, the black arrows are the mounting/ grounding screws. Any one of them will work for a ground point. Not all cluster housings are metal but these are still the ground for the lighting and cluster.

In your case that's correct as your ammeter (if it has one?) is an external shunt deal. Maybe it doesn't. But DartFreak hijaced the thread LOL.I believe Chrysler had changed the wiring by 78 . There is no heavy wire running to the gauge cluster on this .
