Help Please, 1946 Olds

I am trying to help out a guy who has a stock 1946 Olds model 76. Does anyone know or have any specs on the rear axle? More specifically the rear pinion yoke?
If someone has one in hand there are some dimentions that I am in need of. :
1) ground hub dia
2) U- joint series
3) center of cap to end
4) spline dia and count
5) depth of spline?
Thanks to all who can help.I'm merely trying to help out fellow out.
