This is probably a simple topic but one I don't know the answer.  The distributor cap that was on my car when I purchased it was a two part, an adaptor and a top cover.  I have since put a newer cap on it and am wondering what the purpose of a two part cap is.

There is a YouTube video that explains it, and also shows how you can go back to the smaller cap by removing the spacer.  As they explain it, it’s simply to allow a for a hotter/bigger/stronger spark that doesn’t run the risk of cross-firing to a wrong lead. I’ll see if I can find that.  It was on a videoe about the Dura-spark vs. points…….

[edit: - Ok, so…….I checked— it’s not the same one, but it’s by the same guy. The one that I posted is more about the fallacy of the cross-fire claims.  But, if you go to EITHER video, you get the info, and you can go to the guy’s list of videos and watch the rest of them, too.]

Thanks to both of you for the info, I've been chasing a dying while driving issue lately and wanted to make sure I didn't need the two part distributor cap.  I have just located the probable problem, a cracked bare wire on the distributor pickup assembly.  The videos do a good job explaining the cap situation.
