McMaster-Carr, 932 bronze bearing tube, .25" wall, 1" diameter, 3" long, $9.62. Cut them into .25" thick pucks, replace bushing, bolt down. Replaced every 12-18 months.

There's good reason why every sway bar link on the planet can pivot about at least 1 of its attachment points. Unless you K-Car the end of the swaybar, the links have to be free to move without binding.
