 | | Notice the stock axle, buggy spring, and wishbone-style radius rod with a ball at the rear that pivots in a cup attached to the transmission mount. |
 | | This worked great with the dropped I-beam axles that were available at the time, because the radius rods allowed the axle to move up and down and the flexibility of the I-beam allowed the axle to twist slightly when necessary to accommodate strange torsion loads going up driveways or over speed bumps. |
 | | With a dropped axle, split wishbones, and a stock or F-100 steering box in place, the rod that runs from the pitman arm to the spindle (called a drag link) was forced to operate at an unusual angle due to the geometry change. |
