02 sensors

I just installed new crawford high flow cats on my 2007 350z and found the old o2 sensors stuck in my old cats. Any ideas on which new o2 sensors i should get. I ordered bosch 02 sensors but they sent me 2 different sensors which were both completly wrong. One was for i have no idea and the others connector was the wrong size. I was thinking of splicing it and connecting together, but need to know what else i would need to do for it to be correctly.

there are only a few types of O2 sensors, not sure what the Z33 uses but I'm sure any parts counter or dealer can sell you the right ones, someimtes you can buy universal fit o2 sensors for less taht require you to re-use your old connector
