Yea Gary, you already pointed this out to me and I did not forget. Much of what I do here is really based on helpful advise from you, Ian, and others. Here is the next installment:

I guess a lot of forum members already know that a small diameter distributor needs to be used on a GT40 but again I must thank Gary Gibbs for telling me a few months back because I did not know. (Just like I did not know that the GT40 oil pan is virtually mandatory if you want your engine to sit low in the chassis.) And for that matter almost everything I do has been done by many others, but is mostly shown as a result, not as a small step sequence.

After doing a bit of research I was able to simply replace my large diameter Ford style MSD distributor cap and rotor assembly with smaller GM style units from MSD. As you can see from the picture, the GM style unit has a diameter about 1 1/4 inches smaller. For just a bolt-on fix, I thought this was a huge improvement. If I wanted to replace the entire distributor, even smaller versions are available like the one previously shown in the attachment called “MSD small dist.bmp.”
