I put this setup on my car and it works great! This might vary from car to car as far as bolt length but basically it's a 7/16th fine thread female heim joint.
I bought a kit off ebay but I basically wound up using the heim joint (you can find these online) the rest you can get at Home Depot.
If using Vern's sway bar get this spacer from H D the holes on the ends are big and these fit in there between the bushings
