1947 chevy 1.5 ton rear hub nut torque

[Berndtc426]

I just replaced my wheel cylinders on the rear of my 47 chevy loadmaster 1.5 ton pickup. When I took off the hub nuts they seemed pretty tight. I repacked the bearings while I was in there and noticed that they are the barrel type roller bearings. For what I can find via the Internet they don't like any preload. I'm looking for a torque spec for the hub nut. All I can find is tighten the nut until it is tight and back off 45 degrees. Not sure what "tight" actually means. Also if someone can help me identify what rear axle was in the 47 Chevy 1.5 ton pickups that would be great. Note: it's a 47 1/2 pickup. The same body style as the 48-53 trucks.
