Anyone know the diameter and pitch of the front stud on the Savage mkII?

Looking for where it screws into the receiver.... appears to be something goofy like 5/16 - 32 pitch (or M8 .7 pitch?)

Item 10 in this link: http://www.gunpartscorp.com/catalog/...spx?catid=4598

Any help is greatly appreciated. Trying to rework a stock to fit this...

Thanks
