I cut the flange off a shaft coupler thing and welded the splined part into the end of my steering column shaft.
Here is the completed set-up:
The rack bracket has an angle extending to the passenger side that attaches to the steering damper attachment place. When I clamped the bracket on the driver's side, the end of the angle was about 1/2" out from the attachment place on the passenger side. When I pulled it tight it seemed to pull the shaft in the steering column tub out of alignment. Finally, I used a nut as a spacer under the angle. This may mean that the rack is not precisely parallel to the beam. It seems like this isn't much of an issue.
The angle of the angle might have been caused by the clamp on the driver's side being where I did all the grinding on the beam tube.
