Well, I learned something here: IRS vs swing-axel :: sway bar vs camber compensator. I never had that sorted. My car is IRS so at least I know what I have: a sway bar. Works great. As to bushings, I have a note to add. The polyurethane ones (often red) sounded like a good thing. Turns out: nuh-uh. They are stiffer, so maybe more responsive, if that is even an issue. I dunno. But I do know that stiffer can mean brittle, either after a while (lots of flexing, or just age.) And so the ones I have in back crumbled, as it looks like yours did. The better material is neoprene rubber, so I recommend that to those who might need. I got some that work at my local Do-It-Best hardware store. Seems to work fine..
