Hi Lee,
I just remembered something else I did. The wheel didn't go down on to the steering shaft as far as it should have, so I filed the taper on the shaft below the spines (a bit at a time), and finally got the wheel fully seated on the steering shaft.

Then I had to do the other steps I previously posted. Part of the issue was the wheel is likely 'from the land of not quite right' as far as fitting the shaft, and then the rest of the problem was the switch to the CPP box and rag joint, and shortening the column. In the end, I closed the gap between wheel and housing to spec, and am able to column shift the TH350 I have. Took a lot of tinkering, and installing and pulling the column, as I tested the full fit of the assembly.
Regards, Doug
