Access to Differential Fill Bolt to Torque

Of course it will have *some* effect. Just not enough to care about.

There's only one reason not to use a properly calibrated torque wrench if you have one. If you need to use more than one extension or a universal joint. I trust my digital Snap-on 3/8ths with my life.

This is almost enough to go buy a vintage crowsfoot set on eBay.

You sound like you were in my 2 years of calculus at college. However, the shape of the moment arm does not matter. A five foot crowfoot, or a S looking torque wrench does not matter to the basics of torque applied via force and length of moment arm. At 90 degrees, the desired torque on the center of the shaft to be torqued is still pretty much the same because the moment arm from the handle at the end of the torque wrench is identical to the handle to the center of the nut to be torqued.

For angles other than 90º, check out calculator in part C, of link.

What goes if you over torque the dif fill bolt? The bolt threads, or the dif housing threads? What is the fix if the housing threads are damaged by over torquing?

Diff housing threads will strip first since it's much softer than the steel bolt.
I guess you could drill it out and re-thread with timesert or helicoil but a "new" housing would probably be an easier fix.
