Anyone know what imperial threads are on the 3 Primary case studs which hole it against the engine? Not the alternator ones the shorter ones? They have two threads i.e. One on each end?

Sorry, I read your other post and it says 92-3? Best to put it all in one post so they don't get separated.

Well it's odd but the external end of the stud I wanted seems to be 5/16 BSF 22tpi and the other end Cei cycle thread 26 tip so a strange mix?
Not to worry I now have some BSF nuts to hold on my primary case!
