Cross Steering vs. Traditional Steering
Cross Steering Cross steering is the preferred method for nearly all cross spring/beam axle suspension set-ups. Ford used it themselves from 1935-on; the system suffers far less bump steer and offers a more comfortable steering column angle, it also frees up the much needed foot pedal/bellhousing clearance and cleans up the appearance of the chassis from a side view (very important on an open wheel car.) The Vega steering box is the only thing to consider on Model-T through 1934 Fords, also 1935-48 cars can use a Vega or Saginaw box, which gives the option of power steering for these cars.
Traditional Steering Traditional steering will only work with the following combinations: A 4 Bar suspension used with a 1968-73 Mustang Box, or a Split Wishbone/hairpin Radius Rod suspension used with a reversed Corvair Steering box. You can also use the 1948-56 Ford Pick-up steering box with Traditional Steering. An upper steering arm allows the attachment of a drag link to the driver’s side spindle, which is attached to the spindle with bolts through the upper two backing-plate mounting holes.
