Getting code P0135

Well I have a 2004 Yukon Denali and getting this error code PO135. It says bank 1 sensor 1 oxygen sensor defective. The problem I'm having is finding out exactly which AC Delco part # or GM part #. Advanced Auto parts guy was no help. Any help on this would greatly be appreciated...

Talked to GM parts guy and he gave me some information on the part # for bank1 sensor1. The GM part # 12572705 or AC Delco # 213-1161. He says GM recommends doing both sensors bank1 sensor1 & bank2 sensor1 at the same time. I ordered off amazon $56.02/each dealer charges $140.52/each. Hopefully this can help others out... And thanks for everyones help.
