Hi, I had the newer stock electronic ignition inside the distributor. One day it started to get go bad. The engine would stall and would take a few minutes to restart. Anyway, I replaced the electronic ignition with the Pertronix Ignitor Electronic Ignition. I can't beleive how small this thing is and it works GREAT!!! It installed in about a half hour. All ignition problems were gone!!!! And at a cost of around $85 dollars it was WELL worth it!!!
