You can order a pump right off this site. Just click on the "buy parts" button at the top of your screen. Have your VIN with you because if your '97 is anything like my '94, there were multiple water pumps available, depending on the date of manufacture.

I watched my indy do my water pump. As near as I can tell, the trickiest part is the removal of the fan from the pulley because there is very little clearance between the nut you have to remove and the radiator. If you aren't careful you could damage the radiator. He had built a special tool that amounted to a long thin piece of metal with a socket welded to it, and he used that to remove the fan nut.
