I replaced the pre-cat sensor on my '98. Didn't take pics or do a write-up, but you really don't need one.
It was very basic. Two nuts to un-do, and unplug the sensor's electrical connection. Install of new is the reverse procedure.
I didn't have any issues as described in the link in the previous post. I just used a 1/4 " socket, sorry but I forget the socket size.
