Don't know if it will help you in the USA, but the pump I purchased in Oz was: GMB WP3112 Water Pump and Gasket (made in Japan).

I can help with the procedure - I assume that you will also be replacing the timing-belt and it's components while you're doing the water pump? Either way the procedure is the same. Someone posted a copy of my 3.2V6 SOHC procedure PDF at
