V160 getrag master cylinder size?

[Moose]

Hi,

Im doing a six speed and 2J swap into a JZS160.

Im using a custom reverse swing clutch pedal setup and will be using a wilwood master cylinder.

Just wondering if anyone can suggest a size to buy? Havent had much luck in finding the size of the original supra type.

Cheers

Standard Supra is 5/8"
