Dave- if it's that hard you'll have to remove the CAT and try working on it
in a vice.
If you have access to a welder, and you can't remove the old sensor,and
you can't drill it out , then you can make a new O2 hole with a drill and a
nut.

A spare steering wheel nut is the right size. As long as you make the new
hole next to the original, you can avoid drilling into the catalyst.
