Power steering gear box leaks (pictures)

From 1972 -1976 I must have replace 100 or so of these on Hillsborough County Sheriffs cars. They were all Coronets. I used a tinny sharpened flat head screw driver and drove it between the outer seal area and the housing and just pried the seals out. Never damaged a sel housing. Of course this was after dropping the column and driving the roll pin out and prying the steering coupler back. Piece of cake.
