Torque Settings for Powerbronze fenda extenda

Does anyone know the torque settings for a Powerbronze fenda extenda to attach to the brake calipers on my V85TT?
The downloaded Guzzi manual does not have this information.

What size threads?

Might be a bit generic, aluminium or steel being screwed into.

If they are M10 then its 50Nm (page 166)

just get a second opinion
