I remember the maintenance on my '65 Comet all too well. I changed the points, spark plugs, condenser and rotor once a year (10,000 miles in those days). And if the car wasn't running right I would file and reset the points about one additional time per year. Ignition timing was reset along with the points, plugs and condenser change. I changed the plug wires and the distributor cap once in the 50,000 miles I owned the car.
The oil was 5W-20 in the winter and 10W-30 in the summer. I don't remember the oil change interval but do remember it was often. I flushed and changed the coolant once a year.
Tires lasted 20,000 miles (and were well worn by then). I bought 2 new tires every spring and put them on the front (which is what was considered the right place for your best tires in those days). Radiator hoses were changed once in the 50,000 miles and the fan belt a couple of times.
It was a lot of work to keep a car going in those days. But I never did get into changing the thermostat spring and fall.
