O2 Sensor Location
The original sensor is installed in the first cat. element on the passenger side where the exhaust manifold connects. To make the job easier you will probably need to remove the front end support cross member although you probably can do it without. The 84/85 used the single wire / non-wide band O2 sensor that is inexpensive.
If you are having over fueling and black smoke it is probably not the O2 sensor.
