Spark plug wrench

[Gene]

 My truck was broken into, and amoung tools, they also stole the spark plug wrench. I can't use a common 18mm spark plug socket, the fins interfere.
Called the Honda dealer, they said it's discontinued, what size plugs do the newer Hondas use?

Looked on Epay, they have 18mm wrenches, but I'm not sure about height, etc

Any advice, or does someone have a spare they are willing to sell?
