If you have a sway bar in the rear, the mount for that will be on the inside (iirc) u-bolt, above this plate, but below the washer and nuts. You can remove the whole sway bar if you choose. I won't tell you to do it or not to do it. It will give you flex but increase body roll, so if you feel it would be un-safe for your on-road driving needs, don't do it, just undo both sides and shove it up out of the way.
