How do you remove the power steering pulley from a 1969 ford truck?

To remove the pulley you must use a "puller", I removed my pump first but with the good type of puller you might not need to. The shaft on my pump has a hole in the end with an "Allen" type inset which has nothing to do with removing the pulley. (its not a screw). Remember to flush and bleed your new setup to remove dirt and air.
