The front O2 Sensor is on the rear exhuast manifold. If you take off the heat shield, it will be near the #6 spark plug and the tranny dipstick. there is a wire sticking out from the top. The rear O2 sensor is underneath the car, after the catalitic converter. On GTPs, it is standing straight up on the "u-bend". Im pretty sure GTs are the same, since they both have basically the same engine (3800 Series II).
