I see lots of misinformation on forums regarding using extensions on a torque wrench. This is a good calculator. For using Mac and snap on style torque adaptors (maybe other brands, just never seen any), crows feet, as well as extensions, including angled/u-joint extensions.

Hope it helps someone. I found that a 12mm Torque Adaptor from MAC Tools works great for torquing the driveshaft flange bolts. At 2” long it requires you to reduce the torque value on your torque wrench. Use this calculator for the appropriate value. The Mac tool truck guy told me most of the ford guys use an impact swivel socket for the flange bolts. Either will work.
