Went to E Bay, purchased a MC2100 from a gentleman in Colorado and the distributor upgrade he also sells. Just got it on, still tweeking a bit, but it all seems good. So far it has been an an easy upgrade and the CJ runs better than it did before by a bunch. Good product from a guy who really knows his stuff, excellent service. I am happy and so far so is the Jeep. Haven't had the chance to really shake it out off road. Will post when I do. Thanks for all the help.
