Default Rear 02' Oxygen Sensor Part # Needed

Planning on installing my LG SP headers this weekend. Gonna hold off on the rest of the mods(heads/cam/clutch) til I get into a new house.
It's my understanding that with the LG headers, you use the rear sensors in the front position. I figure I should just go ahead and install new sensors with the headers. I will keep the original rear sensors in the rear location. I am deleting the Air injection system so I know my check engine light will be on due to that. Hoping a tuner won't charge me too much to get rid of that.
Can someone please post what sensors I should order. Plan to order off Amazon so I get them Sat. Thanks

is this just on older c5's?... all of mine are square plug but I'm only using the fronts currently... years ago when I installed my headers I just swapped the rears into the front plugs and have never had any issues... I just bought new ones for the heck of it, after 13 years I'm sure new ones can't hurt

Well my 2000 has the two types. Just looked up a 97 and shows two different connectors.

LG sent me the adapters to use the rears in the front locations. I just turned 70K on my 97' so figure I should go ahead and replace them while I'm there.
