Stock TJ control arm bushings. Get them out of some free control arms. They'll press into some 2" pipe, think it was sch40. You have to weld a bead around the inside on one side of the pipe, it'll make since once you look at them, the bushings have inner and outer steel sleeves. I also tack the outer sleeve to the pipe.

Spending $20/bushing is for suckers. The YJ spring bushing thing also works, and keeps you from falling into the "suckers" category. Of course I guess you're the working man anyways....
