LM317T Voltage Regulator with Pass Transistor

This is my 1978 Mercury Grand Marquis...has 275000 miles on it (375000??) and still runs very well. It has a 400 CID engine with FMX automatic transmission. It has had all of the brake components replaced including wheel cylinders, rubber lines and master cylinder, new carburetor, valve cover gaskets, voltage regulator, alternator, starter solenoid, radiator, fuel pump, tires and wheels, new belts and hoses, and I added a gauge package to it as it does not have any factory gauges except fuel. The factory Philco-Ford 8 track radio still works well! It has driven to Abilene and the Dallas metroplex many times with no trouble.
