Quick Q, 1990 NA O2 sensor R/R

Am I going to have to drop the exhaust to get it off and replace it, or is there some magic position/contortion behind removing it?

No magic or dropping of the exhaust. Some spray penetrant, an 02 socket, and a long extension are all you need.

On the stock manifold.... It's right there. Just use a o2 socket and PB blaster (make sure the exhaust is cool or you will have some fun). A breaker bar MAY be needed.

Thanks. Didn't get the opportunity to get the socket today (used a slightly oversize deepwell)...but damn, that thing took the biggest breaker bar I had. Will be getting that wrench with the sensor though.
