In the lower left corner the above show the componets of the M1D mount. I can not find the dimensions of the mount screw. Does anyone have a scaled drawing or know the dimensions of the screw. I know the screw is 5/16x32. The one on my mount is 5/16x28. I would like to try to have a new one made but need the specs.
