Can't find the factory torque spec for this bolt. Should I use the standard 55 ft/lb for a 7/16-20 Grade 5 bolt?

The Lwr mast jacket bearing clamp or coupling bolt is 32 LBS. FT.

Is that the lower mast coupling in my photo?

I did find the spec for the rag joint-to-steering box clamp bolt. It's 3/8 NF and torque spec is 27 ft/lbs.
