Oxygen Sensor

[Jay83Bronco]

Got a o2 sensor at the local parts store. It does not fit. Really big. I have a 83 Bronco with 302 and 2barrel. I have tried 2 different ones any ideas. The y-pipe looks stock but have had everything else back replaced. And I need to past emissions. I have done a full tune up do you think I even need one.

I don't think you need an )2 sensor on your 83 carbed motor, doubt it even had one stock. If you've done a tune-up and cannot pass smog, look at your carb for the problem. Might need a rebuld kit or overhaul, but not very much $$$ for either.
