Installing Gears (Cassette) on newly aquired, used bicycle rear wheel

10 speeds (Shimano Ultegra) being installed on the newly acquired Carbon Wheels (Look brand) with glue-on tires (Continental tubulars).  The installation tool is in place and needs to be torqued to 40 N-m.  I can't find my torque wrench in the overcrowded garage!

Freddy (Local Bike Shop) modified a spoke to fit the missing one and trued the wheel.
