Just responding because you have not gotten a better response ...
If it's a pre-71, I believe your only option is the factory column with the Ross steering. If you convert to Saginaw steering (just like a CJ), then you can pick either a GM column from a Jeep or GM car, or use a hot rod column from Ididit or Flaming River.
I think the 72-73 bullnose has a GM column similar to the '76 and later CJs, but my memory is not so clear on that. So it could have had the tilt option, but I doubt it. I drove a loaded '72 convertible occasionally back in the day, and I don't remember tilting the wheel.
IMO this should be a very low priority issue ... if there were tilt column Commandos built, you almost certainly won't find enough examples so you can pick and choose between them. When you find a suitable vehicle, you can decide whether it's worthwhile to modify the vehicle and have a tilt column.
