What is the torque on the four DS bolts (75ft-lbs)? Also, I should also use blue LocTite?

As for the DS loop...I will be installing via the four supplies bolts/RivNuts per side...Again, I should use blue Loctite on them as well? And, Is there any way to seal the area from water/moisture getting into the chassis frame via these hole. I was thinking of putting some marine sealer under the loop as well as basically chalking all around the loop once it is installed. Is this something (an area) of great concern - not planning on driving through too much water, but you never know.
