Well, you wouldn't need to change the pump, but what do you mean by "So when i went to bolt up the other pulley, the holes doen't line up with the watterpump and it doesn't fit over the existing pulley....."
What hole are you taliking about?? The PS belt doesn't drive the WP...WP is driven by the alt belt. PS belt goes from crank up to tensioner then to PS and back to crank. Is that what you meant?
