The 1960 to 1961 A-Bodies had unique suspensions and little is known about upgrading the brakes of these vehicles. The main difference with these early cars is that they had different pitman, idler, upper ball joints, and drag link, possibly also different tie rod ends. Torsion bars are same length but adjusters are located differently. Since the spindles and upper control arms are the same as the 1962-1972 vehicles, it may be possible to do the upgrades relevant to those later vehicles.
