I had to re thread one of the spark plug holes on my parents for explorer, the thread kit I used, which looks very similar to the one you are showing wouldnt let me get the tap screwed in even with thin wall sockets.
I wound up having to grind down the tap until it fit a much smaller socket. Then to get to the spark plug hole with the ratchet to drive it in, I went through the wheel well, but I had to use 2 feet worth of extensions to clear the fender, so I needed a second person to watch the tap go in so I didnt screw that up. It would have been easier and quicker to remove the engine as it took almost 10 hours, for one spark plug!!!! And I'm also sure that I got some shavings in the cylinder too.
In the end it did work, and now, 40k later that spark plug is still in there
