DisputedSources disagree (sometimes the factory manual disagrees with itself). Every claim is listed with its source.
Procedure

Owner-approved combined envelope of the removal-procedure 7.9–10.7 and top-fabric-procedure 8.9–11.7 N·m ranges; 7.9–11.7 N·m is not printed as a single factory specification. The 1999–2000 manual repeats both ranges for the set plate, so it does not select one over the other.
