I really am impressed with the quality of these arms. 
Got these for X-mas. They come with greasable poly bushings, four bushings per arm (2 per end). everything I have read says that there needs to be some give in our four link rear suspension system to prevent bind. would it be possible to pull the poly bushings and replace with exact same bushings in rubber??? I already called UMI and asked, but they only have the poly bushings. I am redoing my stock rear upper arms with just fresh rubber bushings only. I will not be boxing these uppers. Do you think If I run the tubular LCA with the poly bushings and the stock upper control arm with the new rubber bushings that will give me enough flex to prevent binding? Or should I replace the polys with rubber bushings.
TIA
