Steering wheel nut and horn parts

[samdjr74]

Hi All,

I just purchased a used 68 steering wheel to fit my 67-72 steering column. It didn't include the nut that holds the wheel to the shaft and some of the horn parts. I was wondering if anyone knows the nut size for the steering wheel and maybe have a diagram of how the horn button assembly goes together. I have the horn button, the peices that screw into the wheel but no clue what hold the button to the wheel.

Thanks,
Sam
