From my point of view, I can see no advantage to modifying the steering components in '35-36 Ford, to aftermarket units, Vega, Corvair, etc., when it is so simple to change the earlier steering gear setup to a '37-40 Ford unit..
I changed my '36 Ford steering gear box, worm/sector, to a '37-40 worm/roller in 1955, it was like adding power steering to the car. In lieu of hand over hand truck like steering the steering is finger tip, parking is a snap..
Of course if you are going to modify the power-train with a "belly-button" system, then why not upgrade the whole front end to something more modern...
