What I ended up doing was searching the internet and Ebazon for zerks to get an idea of how many different threads there are.
Then I searched for "kits" that contained ALL of them with straight, 90 and 45 degree fittings. Maybe had to be several kits, too far from my parts shelf to check. There were a couple places on the BH swing pivot that were almost impossible to get to with the factory fittings, so put in a 45.
Gotta be careful as the threads are very similar but DO NOT interchange. Properly. You can jam them in, sometimes, but will never seal. So I've been told of course.
