A little more progress.
Needed three of these assemblies, the stepper is supposed to mount on this with a belt drive reduction to the pinion. The assembly will pivot on the brass bushings and be spring loaded into the rack to eliminate backlash.
The aluminum boss was tig welded to the plate then machined for the bushings.

Free advice is worth exactly what you payed for it.
