You could, but if it's already rusted that bad, replacing it might be a better idea.
It's probably a dealer-only part.

Hit the nuts on the O2 sensor with penetrating oil every day before you attempt to take it off. PB Blaster is a good start to work with. WD-40 is NOT a good choice...thanks for the info I will get under there and snap some pics. I am hoping to replace the 02 sensor tomorrow so I can pass inspection any tips on getting the sensor connector apart it is up on top of the manual tranny.
