Steering Box, Power, Saginaw 700, Variable Ratio, 3/4-30 Spline, Remanufactured. This is a modern Delphi/Saginaw 700 series 3-Bolt steering gear. This will mount to any 4-Bolt Saginaw 700 location. Cars built before 1979 may need a new rag joint connector. This box will install with either flare or o-ring hoses with the included adapters. If you are switching from a manual steering box a new pitman arm will be required.
