I need to know the thickness/stack height of the nut on the dropout pivot bolt, which in this manual http://cdn.specialized.com/OA_MEDIA/pdf/manuals/2010_Demo_Manual_r1.pdf is called Part 2.d. I suspect it's about 6mm or so but can't be sure. If anyone's willing to whip theirs off and measure it properly with some verniers that'd be much appreciated.
