tire valve core size

[fruitcakesa]

Anyone know the core size for 16.9x 28 rear tires?
I need to replace the core on the valve stems on my M.
I don't want to pull the old one till I have a replacement.
I will also post in tires/wheels section

Auto parts guy said they were all the same as far as he knew,
These worked on my rear L3300
