Just wanted to add a modern alternative in case anyone is interested...

printed circuit board...measures 1.5 inches square....attaches with velcro under dash.....I recently put one of these in my street rod for my gauges and works great.....It has a potentiometer on it to adjust what you want the voltage at....simple 3 wires to hookup....input 12V from ignition, ground, and output going to gauges (typically 5 V but can be adjusted)....
