1972 Swinger - 1 1/8" Sway Bar?

OK so I was definitely way off with my assessment that this sway bar is stock. The control arm bracket is thick steel bolt on piece and the bushings seem to clamp to the K frame. The arm itself is 1 1/8".

Sorry my pix are crap because the sun was beaming down behind the car and I couldn't back up far enough to get a picture of the whole thing. From this little bit of photographic information, can anyone identify the setup and point me toward the right bushings?

And yes, this car will certainly be getting a thorough undercarriage cleaning after I conquer the transmission leaks.
