This Borgeson kit converts a manual-steering 1963-1966 small-block Corvette with a short water pump to power steering, using a re-manufactured GM Delphi 600 integral gearbox. The box bolts directly to the factory mounting location and fits the stock pitman arm, delivering a quicker 12.7:1 ratio in place of the factory setup's leaky control valve. Not compatible with the 327 Hi-Po, since the power steering pulley is not correct for that engine.
