96 2.5L 5 speed manual SE. Trying to replace the upstream O2 sensor back up behind the engine and firewall. Removed the coil pack. The Air cond. lines and a wire harness assembly make it very very tight back there.

From the top I can barely get the o2 socket on the sensor. The socket is so tall I can't get a 3/8" universal on the socket cause it's up against the firewall. A 3/8" 180 degree braker bar would fit but no room to maneuver.

From underneath I removed a 4"x4" right angle brace with three bolts. This enabled me to reach up and get better access to the sensor with my hand, but still no room to maneuver a tool.

My next attempt might be with a 7/8" crow foot from underneath. Or, have one person on top turning a braker bar 60 degrees, while a person underneath reaches up and turns the socket on the sensor each time.

What methods, tricks, tools, prayers, have you guys used to replace this sensor???????
