Steering: Application and ID

To avoid confusion when replacing components (993 and 964 parts and, in certain cases, right-hand and left-hand parts), observe parts usage according to spares catalog.
- In addition, check parts prior to assembly referring to:
The identification mark/casting number:
993 (Carrera) parts: casting number starting with 993.
964 (Turbo) parts: casting number starting with 964.
The inscribed part number (identification feature).
Spare part for left-hand side: 3rd group of part number is an odd digit.
Spare part for right-hand side: 3rd group of part number is an even digit.
