1971 Steering wheel mounting nut

I would like to replace my steering wheel nut, it's slightly damaged and hard to screw on the shaft
I don't find much on internet, and mainly for Ford or GM. And it seems to exist different nut sizes depending of the year of production.

I'm lost. What are this nut specifications for 1971?

Is this one ok?
