I was wanting to do the duraspark II swap on my 68 mustang 200. I have seen a couple of websites describing what you need but none that I have seen are exact. From what I ave read I need a 1978 dist., cap adapter, and rotor. I went on autozones website to see about how much it would cost but I dont know what to order it off of. Can somone give me specifics of what Car and motor I need this from? I know I need the ignition module and wires but I would buy an msd. Thanks, Tommy
