85 K20 - Oxygen sensor?

Getting some minor things sorted out on my 85 K20. It has a feedback carb 350 in it. Should this have an 02 sensor? I'm thinking it should, but when the last owner's put their home made exhaust on it, there isn't even a bung, much less a sensor.

If it should, any idea what wire I'm looking for, or roughly where it should be under the hood so I can put one back in?

I believe there was no O2 sensor until 87' when the switch was made from carb to TBI.
