Mopar Power Steering Conversion

The column steering shaft in a power steering Mopar is different (shorter) than the shaft in a non-power steering car.
Steering Gear - changes in 1973. This affects the pitman arm. Prior to 1973 the output shaft diameter was 1 inch (doesn't apply to the C-Body). In 1973 it increases to 1.12 inches. If you buy a steering gear from a post-73 year car and try to install it on a 1972 or earlier car - the pitman arm will be too small.
Typically, 3 different pumps were used on mopars... they require different lines & brackets to secure the pump to the engine.
Identification of the Mopar pumps:
  • Federal - pressure hose comes out the front of pump, and tapped hole in the end of the pump shaft.
  • Saginaw - pressure hose comes out the back of the pump.
  • TRW/Thompson - has a hex-shaped hole or no hole in the end of the pump shaft. pressure hose is in same location as Federal pump.
Both Federal and TRW pumps can use a cap that appears similar to a radiator cap.
