Hey guys, I apologize for the late response to this thread. I haven't been around to check the forums much.
Anyways, I fixed the URL to all the pictures.
For those wondering how to torque the nut, the best option is to use a bear claw. Most people weigh at least 160 lbs, so at 12+ inches of leverage (length of most torque wrenches), you should be able to manage 140 ft-lbs of torque. It's a lot easier to torque fasteners than to break them loose.
A crows foot will probably ruin your nut. But you might get lucky since not all tools are created equal. If you use a 3/8" drive, you run a high risk of breaking it. Use at least a 1/2" drive. Again, not all tools are created equal, so as the end user, you have to make your own judgment call.
I hope this info helped. Happy tuning! =D
