Help in installing steering coupling.

Well, I progressed to the point where I’m trying to install my steering column back in the car. I have rebuilt the coupler with new shoes and retaining clip, packed it with grease and am trying to figure out how the coupler splines are aligned. I’ve got the service manual, but it doesn’t give a very good description of how to align them correctly. I see a little notch on the steering coupler, but I can’t find any indicator for the master spline that it talks about making sure you match to on the steering box. Anybody give me a suggestion or a picture that will show the alignment of these two pieces? I’m about two hours into trying to figure it out and I just can’t get them to go completely together. So far it’s only been a one-man job because my helper is out of town. Thanks in advance for any tips
