"T-bar" above the gear strut retraction pivot point which swings back
into contact with roller bearings connected to the pedals as the nose
gear down-lock engages. Pedals would push roller bearings against T-
bar which would rotate gear strut to steer.

The roller motion would have to be reversed relative to the pedals so
pushing on the right pedal would make the nose gear steer right.

Strut would have to be spring loaded to keep it centered and steering
dampers would be needed.

That's exactly how the gear on a Navion works, except that there is a
"V" slot to center the strut during retraction instead of spring
loading, and there are no dampers.
