This is the front, The Bolts that hold the front sway bar at the bushings to the frame are 18mm, then remove the bolts from the lower control arms that hold the Sway links to them. I have to tell you tho depending on how aggressive you are off-road you may not see much of a difference by removing the front. If tho you put on a set of Daystar strut mounting plates you will gain down travel by removing the front sway bar.
The rear sway bar being removed makes a big difference off-road and you will see little too no difference in the road handling of your KJ.

The rear bar is the squigly shaped bar at the bottom of the photo

The rear sway bar bolts on to the rear lower control arms, you can see where the bar used to mount towards the body end of the lower arm in this photo.
