I need two front O2 sensors for the 99 stang. I think any late model ford ones will do…let me know what ya got…i need these today if possible…
how about mil elminator? i have those so u dont need o2 sensor 
edit…MIL Elims. wont do me any good…my harnesses off the O2s are whats screwed up, not the O2s themselves. Also not worried about a CEL with the OR pipe…or the need for the O2s…SCT X-Cal2 takes care of all those things.
just take them out of your car, put them in the kitty crate and bring them to me LOL
if you cant find any used, i can hook you up at advance auto for some new ones made by Bosch, I can get you a commercial account discount.
