Harbor Freight has a "pulley puller" set (~$15) that worked on my p.s. pulley. Often the rebuilt pulley comes with a bolt and nut to install the pulley. That is all you need. Getting them off is the hard part. If you use a press, do that before you put the reservoir on.
Casaroonc,
His pump is either the TRW or the Federal pump. They look almost identical from the front and I don't know the markings. TRW was used on small block V-8's until ~1970 on cars w/ a cast-iron water pump (lower hose on driver's side) and Federal or Saginaw on ~1970+ small blocks. TRW pumps have 2 bolts in a long channel on the rear. As I recall mine, TRW pumps have an inverted flare high pressure fitting and Federal pumps an O-ring fitting, but may vary w/ year. The other end on the steering gear's valve body also varies. I had an early one (small shaft) w/ a male flare fitting and a later (large shaft) one with an O-ring fitting. To be safe, measure your fittings. Autozone's site detailed the ends and also had the best prices when I bought a power hose several weeks ago.
