Happy late Thanksgiving. I can't seem to find the inner primary to engine torque specs for the front 3 bolts.

That is because H-D never posted torque specs during the Panhead era. Use a standard torque chart (make sure it relates to aluminum) if you feel the need to have a number. Or use a number for a late Shovelhead, same thread size and pitch into the same material.

Be sure to Loctite(blue) or use the factory tab lock on the bolts.
