I'm not exactly sure what "torque" the big nut needs to be, but I have always done mine "just a little more" than finger tight. An old timer told me that if you tighten too much, it will take out the wheel bearings, too loose and you will have play. The bearings/races are dirt cheap for these old girls. Just make sure you buy good quality bearings (made in USA) and pack properly with grease.
