i used the mancini aluminum bushings on one dart, i think they were poor quality. dont recomend them. the slid into the spring eye and you could literally slide the spring on them in the car. the steel sleeve was like a piece of emt conduit. paper thin. they could have at least put a shoulder on one side to lock them in place inside the spring mount. the ones that came with the caltracs for my other dart blew them away. oh yeah i tried thier aluminum shackle bushings, they didnt even fit factory shackles. customer service sucked on that deal too. with my duster i tried something i never heard anyone using before, afco nylon bushings. they have a nice heavy steel sleeve, they have a shoulder so the spring could not slide on them like the junk from mancini. they were fairly cheap too. my shackles were bad too so i used the HD prothane shackle kit with poly bushings and sleeves that are supposed to be a real stiff piece and take out some body roll.
