Thanks for the responses. The issue is difficulty in getting the points gap set correctly because of my ham-handed mechanical skills. I replaced the points (rotor, condenser, cap) because I have owned the car for 3 1/2 yrs and thought it would be a prudent thing. Being a mid-60's Pontiac convert, where you set points externally w/an allen wrench, I find the Ford set -up difficult to accomplish succesfully!
The car runs well. The Accel wires make it impossible to remove the dist cap w/out removing the plug wires, so it is time consuming to go under the cap and reset the points. This is the rationale for considering the Pertronix conversion.
Basically, this is a laziness issue on my part!
Thanks for your patience, James Q
