After Market Steering Wheels

[roadster68 <roadster68@shaw.ca>]

I need some help w/ mine.  I am taking it apart to check wires, ground and 
to clean contacts etc.  The steering wheel is quite old and says made in 
"France".  Does this mean it is not a Grant that everyone talks about.  I 
have removed the horn cover and a main bolt and locking washer.  Nothing 
gives yet.  Do these wheels typically thread on to the roadsters upper 
shaft?  I can't believe the nut I took off is the only thing keeping the 
wheel on.  Help!!!  Larry.
