i used that calculator to determine the torque of a plain, [unplated, non lubed] 3/8-16 grade 5 bolt.
it came in as 31ftlb. i had suggested 25-30ftlb.
if i were to be installing the snubber plate, i wouldn't worry too much about what torque value the FSM states. i would just tighten it good with a medium length 3/8 drive ratchet and call it good. having installed [quite] a few of these over a 50+ year span as i have described, none have ever come loose, or have had any bolts broken or stripped threads in the housing.
however, one could always revert to the tried and true method of part installation that has worked forever. "tighten it up until it strips or breaks, then back it off 1/2 a turn."..........[i couldn't resist.
