Lesson Two: Gruppe-S is hit or miss when it comes to parts. Some people here have had some issues, others have had nothing but good luck.
That said, Mike from Gruppe-S is on the board here occationally, and has a record of going the extra mile to take care of issues. Send a PM to GST Mike, he can probably help you out.
