You will need to shorten the shaft for your installation. You will need to use the same pulley you have now. You will not need the press to pull it. Unlike the one the book talks about, this one bolts on.
If you have access to a press you can save lots of money shortening one from the auto parts store. You just press the hub to where you need it and cut off the eccess shaft with a cut-off wheel. The local high school shop teacher might let some student do it for a donation of some shop supplies.
