They are all threaded studs and you have to grin and bear it and back them out normally. One thing you should try if you have it, is cook them until they are red hot...they'll come out.

I got lucky...mine just came out on their own.
I used to own two CJ's...Perhaps a 3rd is in the future?

Soak them up for a couple of days in penetrating oil, keep doing it for a day or two every 6 hours. Best way to get them out, then when you loosen them a little, then tighten just a little, same process over and over. to try to break free the rust, if not heat them up like the other post said and grin and bear it.
