OP,
If you are handy putting a new IEC 320 end on, and either of these is smaller than your current connector, they would need a hole of about 1.75" to pass through.

I have several Furutech ends that are at or in excess of 1.5" diameter and needed 1.75" holes to pass through a custom built wall unit.
