but why go backward in technology when for the same price you can get the newer distributor that does the exact same job and is more reliable.
In 1973 Chrysler replaced the points type ignition with an "electronic" type. Instead of points opening and closing to complete a circuit, it features a stationary contact which passes current to a rotating reluctor, set at a fixed distance. Since this system has no contacting parts, an electric current is a constant amount on each pulse, and can be much hotter, for more complete burning of fuel. Since there is no point bounce and no parts to wear out, it not only gives a hotter constant spark, but also eliminates almost all maintenance. It also offers increased secondary voltage and current for improved starting and will keep the spark plugs cleaner and give greater plug mileage as well as increased performance throughout the whole RPM range. AND YOU WON'T HAVE TO CHANGE POINTS ANY MORE.
