If you create a signature with your vehicle information in it, we would not have to ask...What year is it?

To my knowledge, there is only one part number for the O2 sensor for your year. I highly recommend getting AC/Delco (part# AFS105), not Bosch or Denso.

http://www.acdelco.com/index.jsp type in your zip in the parts store, not the service center.

I just found amazon.com has them in stock for $55 shipped also.
