This Borgeson integral power steering conversion for 1958-1964 full-size Chevy cars uses a remanufactured GM Delphi 600 integral power steering gearbox, the latest generation of integral power steering gearbox technology, with true modern power steering feel and a quick 14:1 ratio. The box bolts directly to the factory mounting location and fits the stock pitman arm. A new universal joint and steering shaft are included to connect to the factory 3/4in.-36 spline column coupler, and the kit covers everything needed when switching from a 605-style conversion box. Cars with factory power steering will require a drag link adapter or a manual center link.
