Question on Stud Centerboard Mounting Brackets Studs ... length ?

Thread starter #1
I need to get a precise measurement (preferably in milimeters) for the LENGTH and diameter of the studs (outer and inner) on the centerboard mounting brackets which run through the centerboard and allow the centerboard to pivot in place.

I am having them made and cannot gauge the length appropriately from pictures I have graciously received from one of the members of the forum.

If anyone has them handy, I appreciate your help in providing these measurements.
