Nope Jim, same size hole, they are interchangeable. Be aware, the
tune up parts, for the large distributor, are MUCH more expensive
than the more common, small distributors.
I believe that they were used on some commercial engines. The racers
liked them, supposedly they were more stable at speed, but I never
checked one in my distributor machine, to verify that.
That said, they are easier to work on and as I recall, the points
are a bit easier to set, also.

Hopefully someone knows more about the big

using either a large or small one if they are
I have wondered about this, and it seemed relevant to this
