[Healeys] Moss Chinese calipers thread size

[Freese, Ken]

Anybody know the thread size of the bleeder screws for the Chinese BJ8
calipers? The wrench hex is 10 mm and what protrudes from the casting
seems to be just a bit under 9mm or .343 inches. A stock caliper is
1/4-28 thread. I don't want to remove the Chinese screws until I have
new Speed Bleeders in hand.
If I can't get a better pedal tomorrow, I will have to get the Speed
Bleeders or rebuild my old calipers.
Thanks,
