I have removed/installed the steering column on my LHD FHC and it is an awful job to do alone. You really need 3 people, which of course the factory crew had. I think the guy that wrote the procedure in the manual never actually tried it, or did it on an OTS. I believe the OTS is easier, if perhaps only slightly.
One holds the weight, one guides it through the dashboard, and I recall having to pull and bend the front fender forwards a bit.
Leave the drop arm on. The inner lower valence is of course off. The tie rod maybe you can leave on, but I don’t recall specifically.
RHD has a spacer under the RF engine mount so the front carb will clear over the column.
