How do slants fit in righthand drive cars?

Let me clarify: I understand that the engine goes in there, right side up and bolted in. But things like the steering column and, to a lesser degree the master cylinder (especially if there is a booster) would seem to be a tight fit. Mounting the steering box in a different place, as YY1 points out above, would make a difference. It's already tight on that right side...
