Joe,

The polyurethane bushings come from Australia, a gentleman named Paul Grey euro635@hotmail.com.

He lists bushings for BMWs at

I have installed them on my '83 928S upper control arms, but I am still reassembling the car. I was planning to post my results as soon as I finished. Since my wife is due with our first son in November, my project has been progressing slowly. That P word!! (Priorities, I didn't want anyone's imagination to run too far).

Good luck and let me know if I can be of any help.
