Well, not quite.  On the two or three I have messed with, the rivet was
a rivet, and you don't need to replace it with anything, either.

Anyway, the easiest thing to do is to cut the "channel" in half with a
dremel.  Once it's gone, the loosening/adjustment nut is exposed.  I
like to swap in a dist clamp from another engine without the rivet and
stuff, just to make it prettier.

You can also get the channel off by brute force, if you can get a big
screwdriver or pry bar under the edge of it.

Also, as Ben said, you drill out the rivet head.
