Pull them to 77 pounds and then pull them a further 90 degrees. If the truck has any mods powerwise then you can pull the bolts to 80 or 85 pounds and then 90#. You could just pull the bolts to 110 or 120 pounds but I dislike this method because of the risk of a bolt binding and giving a false torque reading. Pulling them to a lighter torque and then using degrees is more accurate as it elimanates any binding issues.
