I have a 1995 E320 Cabriolet and the drive shaft of the driver's side power seat is stripped and I need to find a replacement. I learned that the seats for this model were exclusevely made by for MBz by Ricarro and that they have a unique drive system that is shared with no other models. MBz list the part, but no longer can supply them. I have given up on trying to find one at a MBz recycler. Any ideas out there?
