hello i have a 76 spitfire that the po put in a mallory dual point distributer and i was thinking of putting in a pertronix ignitor electronic system in it. i know moss sells one for like $150 but i can order from pertronix cheaper but i cant figure out which one it is on their website. does anybody know what part number i would need? has anybody had any experience with this setup? any advice or suggestions would also be appreciated. thanks...
