Quick S14 T28 banjo bolt question. Assistance appreciated!

[TAP240]

*yes, I searched..google, nicoclub, and here and came up with nothing solid* lol

I just need some quick assistance; what is the size of the banjo bolt that goes into a stock journal bearing t28? I've found several possibilities, but nothing definitive :bash:
Is it M11x1.5, M12x1.25, or M12x1.5?

Thanks in advance!
