Specifications

Power Steering Conversion Box; 49-51 Mercury Full-Size Cars, quick 14:1 ratio and firm modern feel. 11/16in.-36 spline input shaft.

Borgeson now offers an integral power steering conversion for your 1949-1951 full-size Mercury car. The Borgeson conversion box is a modern integral power steering gearbox that provides true modern power steering feel, feedback and a sporty 14:1 ratio. Borgeson has manufactured the power steering conversion box to bolt directly to the factory mounting location and includes a pitman arm to fit the stock steering linkage without any interference or modification of the frame. The original factory column will need to be shortened for clearance power steering box. Not recommended for 3-speed manual column shift cars. Cars with factory power steering will require either a drag link adapter or a manual steering center link. Eliminate your leaky control valve and feel the road with a new integral power steering conversion from Borgeson.
