I have a “snakey” set of 1.75″ headers on my hot rod truck. Several of the spark plugs are nearly impossible to access. I took an extra 5/8″ socket, though the concept would work regardless what size hex. I trimmed it down In the lathe and drilled a 1/2″ hole through it. Now I drive it with a 3/4″ Wrench and can sneak it in and out.
