72- 340 power steering.

A story was told to me a long time ago from a guy who was in the know. When it came to the assembly line and they went to the bin to grab a part (say power steering pump) and the bin was empty for that model. They would grab another from one from a different model just to keep the line moving.
My power steering pump (federal) calls for flare fitting on the pressure hose, only to find out it uses an O ring type. They used a pump from a different model. So you never know what they did back in the day to keep the line moving!
