Does anyone know off the top of their head what size in mm the large crank
pulley bolt on a waterboxer is?  Also size of rear axle nut on Vanagon?

Thanks in advance for all help.

Bolt for 3 groove pulley: M20x1.5x45x14*
*(don't know what the 14 means hear? Thread tolerance perhaps)

   Single groove pulley: M20x1.5x31,9

Rear axle nut: ***M40x1.5** Should Read: M30x1.5.....
