Can anybody show me where they are? Shoebox has a picture here since his is a 95, shouldn't they be the front?

 

Driver's side is in the Y-pipe, passenger side is in the manifold right before it goes into the Y-Pipe.

 

Uh oh... hypotheticaly speaking, what would happen if I were to, say, drive around without ANY O2 sensors....

 

Hypothetically if you did that the car would run like complete crap because the air fuel ratio would we messed up. If you've already done something to them and you've been driving the car around and not felt a difference, you probably didn't remove the O2 sensors.
