Dear Bruce,
The pictures did not come out very well,but we went to the website and found them. Nice project!
Looks like you'll need a three u-joint system,with two shafts,and a support bearing.
The shafting would be 3/4in. in diameter,while the u-joints are 1 1/2in. in diameter.
What we will need to know,is the diameter and spline counts of the column and box(rack&pinion).
We'll also need to know the distance between the end of the column and the rack.
Our 3/4dd shaft is easier to work with,and would probably be the way to go.
It is also available in polished stainless.
Best Regards,
