My 1992 has one in each exhaust pipe between exhaust manifold and the cats. A little friendly advice: spray old O2 sensor with rust-buster(any kind) the night before when cold. Soak the threads good. Next day, start up your Vette and let it warm up to operating temp. You want to remove the old O2 sensor when the exhaust is hot. Remove slowly and try not to burn yourself. Once removed, be sure to coat the threads of your new sensor with GM anti-sieze compound #5613695. If you use any old anti-seize compound, you run the risk of the sensor not grounding properly. Torque to 30 ftlbs.
