Congratulations on the new car Ken, looking forward to photos in due course!
The steering column shroud that you refer to is the only thing that in my opinion spoils the interior of the current Morgans. I don't know if Morgan had it especially made or it comes from a Land Rover or such like...but while the ugly standard wheel may work with it, most people seem to opt for the MotoLita wheel and you then get that ugly gap. I have bought a new shroud from Allon White. It is a bit shorter than the standard one, revealing more of the boss and has a neat return face on it which hides that gap. Mine was covered in the standard Saddle Tan leather my Sport comes with and bespoke leather will cost more, but its worth looking at what they do.
