Many of those "wells" are so constricted that the single-item spark plug socket/swivel/extension deals won't work--the steel ring surrounding the joint won't fit into the well.
In my case, the black ring won't fit into the "well" of the GM 3.4L DOHC "W" body engine.

I had the same problem with my one. I cut the ring off and welded the swivel pin. Now it works perfectly!
