Well, the outside dimension of the fork is almost 41mm. Then you need 3mm for 2 washers, at least 8mm for the nut, that makes 54mm (M10X55 would be the choice then). Last time the Wilbers guys were not able to incorporate a thread into the fork, which would make things less tight. Make sure you choose a bolt with a rather low head hight. I milled all down a bit to get more room.
