My rear sway bar has a bracket the needed to get bolted to the frame. There is a hole in the bottom of the frame rail. Appearantly some vehicles had a tapping plate in that hole...mine did not. My instructions said to put a clevis braket around the frame and drill a hole in the side of the frame rail. Instead, I used a threaded insert and welded it to the bottom of the frame rail. This mount carries the drop link. The ends of the sway bar attach at the spring perch on the u-bolts.

I don't have a photo handy, if you need one, I will get it but it may take a day or so, my car doesn't sleep at my house. If there are more specific questions, let them fly. Maybe I can talk enough to explain it.
