Bushing brackets are exactly the same. Make sure to lube the bushings when putting this new sway bar in. I have an SE model so it made a huge difference going from a 13mm bar to a 20mm bar. When I did it was around $90 shipped for everything listed above but I believe it's since gone up. Great bang for buck upgrade though!
