I need some help. I am attempting to fit a replacement stock to my 1937 Win. Model 12. This M12 belonged to my dad. The original stock was replaced years ago with a clone and I am going back to the proper period wood. To be clear this is a stock from another older M12. I know that the receiver stud rotates to accomplish cast on or off. I am having difficulty in getting this stud set just right to get a perfect fit of wood to receiver. Any tip to get this set correctly will be appreciated. I have used some sanding to open the through bolt holes but do not want to go to far. Thanks.
