I beg to differ..it most cetainly does have:

a 2-piece pully separated by a rubber dividor. I never said anything about
it being internal. And it will fly apart if you over tighten the belt. I
'know' that because, at the advice of someone in the forums who knew nothing
of the cronic issues with the distributor bearing, I kept tightening the
belt. Eventually the outer pulley separated from the inner hub. Made a mess
of things down there too.

If it hadn't been for the car quitting completely and discovering that
the spark was nearly 180 degrees out I might have put it in the shop. It
occurred to me to pull the distrib cap to confirm that the rotor was turning
when I found it was full of red rusty debris. I could see that it had melted
on the center hub and spun around.(see link at bottom) If you get a handle
on it before it gets too hot it may not destroy the ignitor module in
there...it was too late for mine. I think if you pull the distrib cap off,
pop off the rotor button, and then pull off that dustcover

in there you can get a good look at the outer bearing.

I apologize for jumping to the conclusion that it was definitely your
distributor, and possibly inducing panic. JB was right to point that out.
