Re:Knock Sensor

I'm more confused now than before:

My Bentley, for both the '84-85 Turbo KH and '86-88 MC lists the torque at
10Nm (87 and 88 in-lbs, respectively).  Also, in the Fuel Injection and
Ignition system sections I see by the diagrams what appear to be two different
types of knock sensor:  the type where the retaining bolt goes through annulus
of the sensor (F.I.) into the block and the "plug" type where the wiring is
co-axial with the sensor threads that screws into the block as a unit.  

Do these two sensor types take different torque values?  Is this another
Bentley misprint?
