ring and pinion swap, Torque spec's?

Im switching out the ring and pinion in my 50 chevy, changing from the 4.10's to the 3.55's, i got an old motors manual, but there isnt any torque specs for the ring gear, there are about 10 3/8s bolts that hold it together with the spider gears, any one know what these should be torqued to, my guess is 35-45 foot lbs.? any help is much apreciated

 

On a 9" it is 65 to 85 ft-lbs I think that should be the same for any ring gear.

 

really that much huh? hmmm, i wouldnt think that with 3/8s bolts.......but i know they were pretty tight when i dis***embled it.....

 

Richmond specs from their instruction sheet.
Ring gear bolts:
3/8-- 45-50 ft/lbs.
7/16- 60-65 ft/lbs.
1/2--100-110 ft/lbs.

Carrier cap bolts
7/16--60-65 ft/lbs.
1/2---80-85 ft/lbs.
