Align wheels so they face forward.

Remove horn ringand/or centre cover so steering column nut is exposed.

Undo nut from the column.

Now comes the fun bit. Most column shafts have a tapered fit in the steering boss which causes them to be somewhat difficult to remove from the steering column.

Best method here is to use the palms of your hands and belt the beejeebus out of the wheel at the 12, 6, 9 and 3 oclock positions. This will eventually break the taper and the old unit should then slide off.

Before you fit the new boss kit and aftermarket wheel to the sterring column, make sure your horn adapter and contact point(s) for the hornare setup and ready to go.

Reinstall wheel. n.b. There should be a small dimple on the steering column shaft indicating it is more or less centered (wheel alignments will affect the positioning of the steering wheel relevant to the position of the front wheels).
