Mopar Distributor

I personally have used the Mopar P3690426 and the race unit w/o the vacuum advance for over 20 years without a problem but then again the P3690426 that I used, I put a MSD Cap-Adapt on to it because of an article I read by Dr. Chris Jacobs. For those who are or are not familiar with Jacobs, Jacobs holds patents on many of other electronic companies products including MSD and the Spiral Core plug wires.
