Well you didn't say what third member that you have(stock,aftermarket iron, or aluminum) so here is what I have. This is straight from Richmond Gears instructions that came with my Pro gear set.

7/16" Ring Gear Bolts : 60-65 ft/lbs
1/2" Ring Gear Bolts : 100-110 ft/lbs.

7/16" Carrier Cap Bolts : 60-65 ft/lbs.
1/2" Carrier Cap Bolts : 80-85 ft/lbs.

Here are the specs from Mark Williams for their aluminum center sections

Standard Pinion Nut : 110-125 ft/lbs (max : 175 ft/lbs.)
Large Pinion Nut : 140-170 ft/lbs. (max : 200 ft/lbs.)

3/8" Pinion Housing Nuts : 30-35 ft/lbs.
7/16" Pinion Nuts : 40-45 ft/lbs.

1/2" Carrier Cap Bolts : 70-75 ft/lbs.

Now here are the torque specs that I have with my Mark Williams aluminum thru bolt 9 1/2" center section (MW PN # 57448-95S) set up sheet. I'm using a 9" ring & pinion in it.

1/2" Ring Gear Bolts : 110 ft/lbs.

Carrier Bolts : 90 ft/lbs.

7/16" Pinion Nuts : 45 ft/lbs.

Large Pinion Nut : 160 ft/lbs.

45 ft lbs should be good for those.
