oxygen sensor question
 

hey all. i saw a post on here before but cant seem to find it to save my life now about someone using rear oxygen sensors from a 96-97 car on the earlier ones when using long tubes since they are farther down stream. can someone confirm this for me cause ive been having problems and i need to buy some new ones anyway. thanks in advance

The rear O2s don't have the same connectors as the front O2s, so they won't even plug in.
