Help with Removing NSS

I'm trying to remove the neutral safety switch in on '98 XJ, and it's not cooperating with me. I've tried the prying under the large bolt with a screwdriver trick, and all it's doing is making the nut pop off the threads (thankfully it did not mess up the threads in the process). I've got the shaft area spayed down with PB Blaster, and will let that soak in for a bit. Any other good suggestions to get this switch to come off (can't afford to break it or replace it, and it's my daily driver)?

This one has many threads about problems with this. If you search, you can find them, but all they amount to is different ways to pry lightly on them and stories of people breaking them.
