The OEM o2 sensors have the ACD# stamped into the exterior metal shield, as you may already know. Are the plugs and the wire counts/wire colors the same? If not, buy the correct one, especially if you have local emission tests. Funny how the 96 & 97'* are different as 96 was the year for OBD-2 compliance.
