Use a search term gas-filled strut or E_996_KATALOG.pdf is what you should be looking for.
The lower pin is one of the two listed below. All you have to do is call, email or write a parts department and they should help get the right stuff. Yah they should but good luck.
999-167-049-02 ball pin M 6
999-167-042-02 ball pin M 8
The M6 and M8 might mean milimeters for the bolt so maybe know the bolt sizes.
It also appears the strut is on the left not right so maybe years are different.
