There is also one (or sometimes two) classes of fine pitch threads once you get to the larger screw sizes. I know the threaded holes for the front turn signal mounts on the '78 took a fine M12. The mirror mounts may be fine thread as well.
(The fine pitch is listed second.)
M8 1.25 1.0
M10 1.5 1.25
M12 1.75 1.25
M16 2.0 1.5
