I should not say 'always, or never"....but here is a thought!? Some of the blocks had the bosses, but were not drilled....perhaps @ 1 point somebody drilled /tapped the bosses, & that could be what you are seeing? Any of the factory blocks, that I have been involved with (62-82 on the yrs), car or truck, have been 1/2 coarse thread on the block pivot ball. To the original poster, I would clean the threaded holes with a rifle brush, & shoot a little brake clean in em, as they may be plugged with grime/crud? Longhorn
