Take out the new bracket.
Drill a 5 mm (13/64") hole in the bracket stamp [D] for the mounting in the sun roof base plate.
Install bracket [C] on sun roof base plate so far back that it is in contact with the plastic part of the sun roof base plate.
Important: Place a protective plate between the outer roof and the sun roof base plate so that the drilling will not damage the outer roof. Ensure that the plate also covers the area between the outer roof and the base plate where it is mounted.
Drill a 5 mm (13/64") hole in the sun roof base plate with the drilled hole in the bracket as a template.
Remove bracket.

Remove the protective plate [E].
Install the rear bracket to the roof member with screw P/N 969005-8
