Try Energy Suspension poly stabilizer rod bushings, that is what I'm gonna try when I get to that pointjoel,
i've been thinking of trying automotive shock bushing. think i have some of those laying around and those brackets are about the same configuration as the rubber shock bushing. may be just a little too big, but i could cut them down. may try that today, but also wanted to try and get my new tire on the front today.
