I know this thread is old and I haven't posted for a while. I had put this whole thing on the back burner for a couple years. I just this week got it all ironed out. It took some doing and not quite traditional to say the least.
There was just no way to get what I wanted with the pitman shaft coming out that high on the cowl so I built this drop.



It also slowed down the steering as the sprockets are 11/15. Then I had to extend the steering arm because the tire hit the drag link in a left turn.
Here is what I had.


And the modified version tacked in place.



My drag link is level and I now have full swing on the steering wheel with a little over 3 turns and both spindles hitting the stops, plus I didn't give up any footroom.
