Ever so close

There are 2 sets on 97-99 cars for a total of 4 O2 sensors; the 2 pre-cat O2 sensors which are used for fuel ratio and 2 post O2 sensors which monitor catalytic converter health.

Ok, I'll have to check my info. In the meantime, I removed my post. Thanks.

So what your'e say is that CATs I bought were for MY 2000-2004? My only options are to (1) remove and replace Cats with correct ones or (2) have an insert welded to the existing ones so I can install O2 sensors?

The cats I have in now does not have the spot (#4 on the 2000-2004 diagram) to insert an O2 sensor. Do I have some sort of mutant catalytic converter???

Is there any "Hack to bypass the aft O2 sensor? Will the car start and run with the aft O2 sensors not attached to anything?

All I want is for this project to be over with...
