I used the factory specs (22.5 ft-lbs from what I read here) on mine and even with red loctite they came loose within 100 miles. I called dynamic they said 40-45 ft-lbs. That's with the 5/16 bolts. Don't know if that really helps since you have 7/16 bolts. Know a lot of people that just "tighten the pi$$ out of them with loctite" and don't mess with torque wrenches.
