I have an o2 sensor for ya, but you'll have to extend the wires on it if you're using it as your secondary. If you want to wait a couple weeks I'm taking it out since I'm now cat-less (it's being used as primary o2 right now), and replacing with a shorter one. Let me know. Swapped it in when I did my mini-me swap 2 summers ago.
I will PM you with my offer. Let me know
