I did the re-pining of the ecu and have been running my rear 02's as the fronts and gotten the rears tuned out for half a year now and its been no problems. But this week I got a bad 02 sensor code on my passenger side so I'm going to have to replace it. But I'm unsure if I should be replacing it with pre-cat or post-cat stock 02 sensor? I read their the same other than length, which is no problem but I wanted to be sure I shouldn't be running the same rear pre-cat 02 sensor, or just any sensor.

Just get regular front o2 sensors. Replace the pair. If one goes out, the other is likely to follow.

He is correct. I'm also running the rear o2's as the fronts.
