'94 O2 Sensor vs '89 O2 Sensor

Are the o2 sensors for the later model cars the same as the sensor for early model cars.

I'm swapping headers from an '89 into a '94 and need to know if I need to change the sensors?
 
I do believe....

I think they are different. I know the PCM uses 2 digit codes on 89 and 3 digit codes on 94-95.

I would check with a parts store and ask to cross reference the numbers. If they are the same, good to go!!!
