Distinguishing feature/identification of the stabilizer models
- Sticker (A) with the spare part number (SP No.).
- Production date/calendar week (see text above) in conjunction with the outer diameter, insofar as the SP No. (sticker A) of the stabilizer is no longer legible. The production week (calendar week) is imprinted into one of the two flattened areas where the stabilizer mounts are fitted. Example: 26 9 imprinted. Corresponds to 26th week 1999 (week and year may also stand above each other).
