The way the Packard gauge works is a small heating coil works on a bimetallic strip which moves with temperature change and is linked to needle. At empty, the resistance is high so very little current flows to heater, so very little heat up, and almost no movement of needle. At full, there is only a slight bit of resistance, so the heater is on and able to move the needle to maximum.

Since you have to keep the gas supply line part, from the looks of the setup you have it might be possible to remove the unit from the universal gauge (which is just screwed on) and mount where Chevy is. It might have to have a small plate added so you can orient things properly but by bending & shortening the float assy, it should be possible to reach a suitable range. The JC Whitney univeral assy and part # I worked with is shown. Adjustment at empty would be 70-80 ohms and full would be 5-10.
