To my knowledge the front and rear sensors function the same, they just have different connectors. If you're doing a coversion which only requires the pre-cat sensors, I'm pretty sure you can use either part number but it they will have to be wired to the pcm in the position of the pre-cat sensors. The rear 02s are just to tell the PCM whether or not the cats are still working/in place.
