Wow you got lucky on those gauges!! They run on about 5v. A battery charger or a battery will work just fine to test a radio no the bench.

I have a radio for my 65 Belvedere on the bench. Short of dragging it and speakers out under the hood of my truck to hook it to the battery, what could I use as a power supply on the work bench to see if it works? In the past I used a battery charger to test the guages in my instrument cluster when I refurbished it. Any suggestions?
