Tvr car parts clutch master and slave

[bluetiv]

I have just purchased a clutch master (TVR 035Q 038A) and slave (TVR 035Q 039A) from TVR car parts and they have no paperwork with them to confirm the thread type or what union to fit. I was wondering if anyone on here has fitted these parts in the past and found out what the thread is.
The master has a bung with 7/16 on it but nothing on the slave witch looks larger.

That is most likely 7/16" unf (20tpi)

It has been suggested in the past that the original slave cylinder is M12 x 1.00mm pitch?
