Clutch master cylinder bore?

[Brummmie]

I am p!ssed off with that silly cover, every time I want to service the fluid, I want to put a remote filler in the engine bay.
So anyone know the bore size?

Cheers

No one know this?

If your Master Cylinder has "Girling70" on the side the I think it's 0.7 of an inch.
BUT
You can buy a Master Cylinder with a separate reservoir from here

Alternatively..... Leave the cover off and fill the hole with a Sock

Nice find!! They also do a reservoir extension http://www.merlinmotorsport.co.uk/p549/GIRLING-RES... which looks perfect! I always did think the cricket box glued over the filler was a naff way of doing it!
