O2 Sensor Confirmation

I have a 1991 convertible; can someone else confirm that these only have (1) O2 sensor? I am getting conflicting information, saying that the book is listing 2 for this application. I had an '86 a few years back, and that only had 1 sensor, in the same location very close to the oil filter. I looked all around the exhaust system on the passenger side, and couldn't find another one. Maybe they started with 2 sensors in 1992? I placed an order with Chris May @ Superior Chevrolet, and he wound up mailing me 2 sensors per what his book was calling for. Any help????

Thanks, Chris.

I will have to check, but I thought 1992 was the first year for 2 O2 sensors.

On the 1992, they are near the bend just below the header.
