Where the hell is my O2?

Ok, im pissed, I looked all over. Where is my O2 sensor?

Its a 91 TA with 350 TPI from 89. It has SLP Y pipe with random tech. cats, SLP headers, Hooker aero chamber cb.

Where is it? Or atleast in what area?

It would be in the driver side header, just ahead of the Y-pipe.

Though, only the 50-state legal SLP's have the bung for them. You may not have one.

Yeah I found it. Drivers side. Was a bitch to get out. Old one looked like "chalk". New AC Delco now installed. Lets see how it helps gas mileage.
