Is there a difference between front and rear O2 sensors? My buddy just found an old stock harness he had and it had all 4 sensors in it. They have about 20k miles on them so they will get us both by for initial fireup and a little drive time. Since we're both going with standalone harnesses we both just need the front 2. Are they interchangable? If not it looks like I still have some O2's to buy..
The upstream and downstream should be exactly the same. They are about $50 a piece at parts store incase you wanted to know

Awesome news guys, thanks! I figured they were the same cuz they have the same wires and read the same way right? So the connector is different only? That's why I was wondering why, because they had a different part number that was only 1 digit off
