O2 sensor question

[Chad]

I found the other part numbers, it's an ACDelco sticker on top of the GM
sticker.

I assume the ACDelco number is (there's a lot of numbers on the tag):
    1   #213-805
And the GM number is:
    1   #9120292

I don't know how much they sell for, but it's a part you can get at any auto
parts store, not just from Bosch.
