Those are the same ones Rick Ehrenberg sells on ebay. Hi Rev 7500. I have one on Vixen and it runs great. I think too many people fall for the marketing of the MSD stuff. I also find it pretty funny that if you post you either don't like MSD or don't use it that now suddenly you're an idiot who knows nothing about ignition systems. I can purt near guarantee you I've installed more MSD items than a lot of people on this forum over the years and I still am not crazy about it. The factory Chrysler ignition to me is far simpler and will do the same thing.
