Where do the marks go on a distributor?

How can I tell if a distributor has been replaced?
Assuming you are replacing the distributor, take out the hold-down clamp that keeps it in place. Some of these are hard to see, but locate it and remove the clamp and hardware. There’s no reason to mark the old distributor since it won’t be going back in. Now compare the new (or rebuilt) distributor with the old one.
