O2 Sensor Help

You might try a “box” type crow’s foot wrench.

Is there a trick for accessing the front driver's side o2 sensor without unbolting parts? My truck is not on a lift either. It looked pretty tight up there! Even if I could get it unscrewed with the o2 wrench, unclipping the wire looked challenging.

If I remember correctly, I did my driver's side through the wheel-well or from the top but I had all of the heat shields off. Going off what I remember, there is almost no room up there to access it without removing parts. Sorry, I can't help more, I did not remove the O2 sensors, only unplugged them when I was working on the manifold gaskets.
