Prop Shaft CV to differential flange bolt = 44 ft lbs.
Prop Shaft Coupler to differential flange bolt = 63 ft lbs.

The Service Manual shows a pattern (sequence) to tighten the 6 fasteners that is 12 o'clock, 4 o'clock, 8 o'clock, 2 o'clock, 6 o'clock, and 10 o'clock.

The Service Manual says:

Thoroughly clean the threads using denatured alcohol, or equivalent, and allow to dry. Apply threadlocker GM P/N 12345493 (Loctite Red), or equivalent, to the propeller shaft-to-flange bolt. Ensure that there are no gaps in the threadlocker along the length of the filled area of the bolt. Allow the threadlocker to cure approximately 10 minutes before installation.
Tighten the propeller shaft coupler-to-transmission flange bolts and nuts to 85 Nm (63 ft. lbs.) .
