Heat Shield and 02 Sensor Removal

I've read every thread I could find on removing the heat shield and couldn't find a definitive answer to a question I have. Can the heat shield be removed without removing the 02 Sensors? I removed it off of the 01 I used to have many years ago when I was gutting the precats and of course removed the sensors then but don't recall if there was room to pull off the shield with the sensors still installed. I searched around for pictures of a shield that had been removed to see the room around the sensors but didn't see one. With time on my hands these days I thought I'd remove and paint the shield but don't want to mess with the sensors unless I have to. Thanks for any info on this.

Why is that? It appears there's enough room around the sensors for it to pull straight off as long as the wires to the sensors are disconnected.
If you gotta you gotta though. I got the top two bolts out already and will next attack the lower two next. Just didn't want to have to mess with the sensors if it wasn't necessary. There's an O'reilly's nearby so I can go get a loaner O2 sensor socket there. Thanks.

I just did this on mine. The plugs on the ends of the O2 sensors are to large to fit through the holes in the heat shield. Also, at least one of the O2 sensors blocks the removal of the top shield. Use some break free spray (pb blaster, maybe) and invest $10 in a proper O2 sensor socket. Take the oppurtunity to examine the sensor tips for condition, and see if you can photograph the tops of the precats, see if they are in ok condition. It turns out, one of mine is breaking down, I'm going to remove it soon.
I neglected to mentioned, even though I sprayed the top two shied bolts with break free spray multiple times daily for a week before I began, one of the bolts sheared off anyway. Just ordered a metric tap and die set to take care of rethreading that hole...

It's a coax line that goes to a dual band antenna situated on the rear edge of the engine lid.

That engine lid is a terrible place for transmitting... Especially with LED bulbs that throw all kinds of interference.

When I can't activate a repeater from 12 miles with 45 watts, there is a problem. There just isn't enough flat sheet metal on this car for what I want to do...
