Model A Steering box adjustments

[wings515]

Hello,
This may sound strange but I have a 1939 Plymouth PT81 Pickup. It uses the same Gremmer steering box as the model A. I had an A and it struck me that it used the same box as Ford.
In any case, I have read and re-read the Ford instructions for adjusting the box without success. If I get the "center" adjusted so there is no slop then at the 2 o'clock position of the wheel it is bound tight. If I fix that, then there is an unacceptable slop when driving straight.
I have had the box out and in the vehicle too many times that my frustration level is at a point of 'give up'.
I noticed a suggestion of a complete re-build for $600. Does anyone know who does this and how to contact them.
Any help would be appreciated.
Regards,
