I have both the Pit Posse Silver Red and Black and the Georges Garage. I use the GG to torque the nut and the PP to hold the left side to keep the axel from turning. Much easier to torque with the 3/8 hole lower on the tool.

 

If you are questioning the correctness of your torque.
Locate a 3/4-1/2 " long bolt to fit your 36mm rear nut.
Attach them to your bumper or any hole of your choice.
Torque it to spec. (or 100 lbs. to make it easy) using your skinny wrench with your torque wrench at 90° ( this is correct).
Now attache your favorite 36mm socket.
Retorque the nut, you will have your answer.

That is all
