Thanks for posting that image. I started a new thread to try and clear this subject up. I'm going to highlight the bung wholes with sensors in red. Maybe the model year is actually 97-00 and not 97-99 for the single set of cats. You would still have sensors right after the headers and inside the cats before the muffler. Look at my picture in the new thread I started.
