As previously requested - because of my ignorance I striped the nut that is behind the plastic nut on the side of the sunroof motor assembly. I put a 17 mm socket on it and turned it in order to manually open and close my sunroof and after a few cycles it striped. This nut has a fine thread and I can't find a replacement anywhere. Visited hardware stores, plumbing stores, a machine shop and also contacted a MB dealer. -------------------------Can anybody sell me a replacement nut???
