Got home and pulled the distributer cap for the first time in the 15 months I've had this cobra and was horrified to the the rust in my pre 2009 MSD dizzy and one of the advance springs was broke, lucky it hadn't fallen down inside the distributor, just one of the small ears. Now I have time to replace the 15 YO unit before serious driving weather arrives. Now to figure out what is the "best" solution today as I can't believe the number of material quality issues MSD has across all car of this vintage including Mopars, Chevies and Fords...

We have had good luck with the Pertronix distributors. Self-contained (no ignition box needed) and available with an adjustable rev limiter. They also have "factory cast" units that are not billet so they look like an O.E.M. Ford unit. And they have OE type caps in BLACK!
