Pulley removal & reinstall?? How to??

Working on Fern our 75 dart /6 auto ac power steering pump.
I believe the one with the filler neck is Federal???
How do you take off the pulley for swapping in a new pump? It showing 4 different specialized tools in the shop manual!
Can't use a wheel puller?
How do you guys get the pullies off when you're doing a new power steering pump swap??
Why can't you just get one with a pulley already on there?, sense mine is rusty anyway??
Please advise & Thanks!8)
