Have you looked at this page from miata.net?

http://www.miata.net/garage/cas_oring.html

One other page mentions that it can be hard to get things lined up
again, and that the new, fatter o-ring will be harder to push in than
the old one.
One of the articles also mentions that the sensor only goes in one way,
basically that you can't put it in backwards. If you have lost your
alignments marks, it should be an easy enough job to reset your timing
once you have it all back together.

Good luck!
