Has anyone else had problems with their electric seats not moving forward and back because the brass bushings that attached to the threaded rods under the seat broke? If you have, are you interested in getting replacements for those brass bushings? I had a machinist make the brass bushings at a cost significantly less than the $1,250 cost to replace the right and left seat rails - Porsche's solution for the problem. If you are interested, I have a couple that are available for sale. Let me know at email@example.com.
