You can pick up new shock bushings at O'Reillys & Autozone. More likely Oriellys, I think they have the rubber ones instead of poly.
As a general rule, unless there is something really custom about the shocks the bushings are pretty much interchangable.
06 Rubi with some sort of double ended, chrome knobbed, cross threaded, infinitely adjustable, frequently breakable, worn out flammywhammers zip tied onto it.
It used to be a jeep thing... til that sh!t broke!
