Yes, the outboard bolts on the rear main cap are a smaller thread. The threads should be clean, and lubed with 30 weight motor oil, also. If a high pressure lubricant like hypoid gear oil or Never-Seez is used, reduce those torque specs by 10%. I like to use a drop of lube under the head of the bolts, as well as on the threads. "Torque" is simply a controlled stretching of the bolts to prevent them from backing off due to vibration. There is also a different torque spec for grades 2, 5, and 8 bolts with the same thread.
