My '08 is a 36mm or whatever the SAE equivalent is, I believe it's 1 7/16".
Yup, that was it....1 7/16". I looked in some boxes full of misc. junk I haven't used for years and I found a 1 7/16" socket that I bought about 40 years ago to remove the nut off the end of the crankshaft when I overhauled my 1966 VW Bug engine.
