So I'm constantly getting the P0420 code on my 2000 Durango 4.7L with 189,000 miles. Original O2 sensors.
I haven't looked yet but I figure I have one O2 sensor pre cat and one post cat being that it's a non California emissions setup.
No idea which one's to get from Rock auto website or how many:

Like HeyYou said, unfortunately, your truck will have 4 in all, two on each bank, so you have to get upstream and downstream for each side. Stay away from Bosch.
Mine haven't complained even with 306K miles. I'd like to replace them cause I know it's overdue and I'd like to see their effect on gas mileage, but it's four of em, so recovering the cost in fuel savings would take forever. Personally, I'd remove the plastic fender wells for the upper sensors. The sacrificial clips and tool that hold the wheel well in can bought at Harbor freight, but zip ties have worked really well for me.
PS: Start spraying them with PB blaster from now and let it soak in overnight before driving. Dakota and Durango procedure will be the same.

Hopping in on this question, but its kind of an off shoot...HeyYou mentioned NTK or Denso brand, does that translate to other sensors such as Idle Air Control for brands? Did not see a "Mopar" branded one of Rock Auto...
Sorry for the
