Stop in for a cup of coffee
That Pertronix mod took a while. Pertronix didn't have a application for that distributor. They wanted me to send my dual point out and they would see if they had something that would work. I didn't want to risk that so I bought a matching distributor from a member here (from Canada) , got it and sent it out to California. Pertronix came up with a unit from the late 50's Hemi that worked. It took a while but I got it figured out. There's a sticky thread in the ignition forums about it. Nothing is simple with these old Mopars!
