Steering Box Universal Coupling Sizes
Since I'm converting from power steering to manual I got the longer steering column & painted it the correct color. It did not include a universal steering coupler......
I was in the process of using the power steering coupler when I discovered the fitup problem. It appears I can get a new coupling from:

Assuming the manual box I was sent is correct with the .723 diameter input spline & the above advertised new coupling is correct I have the solution.
The incorrect EBAYad listing both the manual & power steering couplers as interchangeable threw me off.
