Default Dakota R/T Oxygen Sensors

Hello all. I have a 99 Dakota R/T CC, originally sold here in California. It has an o2 sensor coming off of each pre cat, as well as the two downstream sensors, one on the cat and the other post cat. Which ones are most critical to replace at 130k miles? The one located on the main cat? If so, does anyone have the appropriate Delphi or NTK part number for that sensor? Rock Auto's selection is a little confusing it seems.

Are you getting any codes? How's your mileage?

O2 sensors aren't exactly something most people replace as "preventive" maintenance. There's no reason you couldn't though. They can get "lazy" as they get older.

NTK is the OEM. Do NOT use Bosch, there are way to many people that have had problems.

It looks like: NTK 23506, 23151, and (2) 23099

Mileage is ok. Averaging 14-14.5 per tank on 89 or 91 using SCT/Hemifever 87 tune. Roughly 260-270 miles per tank. Runs pretty well too. Running 275/65/17 tires.
