I will try to see if I can find the tune-up specs for your engine. The numbers I gave in my example are close but not exact. They do make distributor re-curve/repair machines for rebuilding them but lately, a person who knows how to do it is a dieing breed, racers used to use them to optimally set the advance curve on a distributor. More than likely the bushings will be worn a little if your distributor is as old as the car. If your car is a street car and after geting a good tune-up it runs well I wouldn't worry about the wear on the distributor. The distributor really doesn't have anything to do with the strength of the voltage spark, that is more determined by the coil. Again, if your car is street driven and stock all the way original parts (or replacements) will do fine. The distributor "distributes" the signal to the appropriate spark plug/cylinder hence it's name. A good tune-up does wonders for an engine.
