Clutch master cylinder size

[Simon]

My car had the renault gearbox/adaptor plate setup but will now be fitted with a full size bellhousing and a 10.4" clutch but still utilising the renault slave.
The original master cylinder was a .625 (5/8ths) bore. Could anyone with a standard renault slave and full size clutch let me know which size master cylinder they are using please?
Thanks

Simon

I run a 7/8 (22,23mm) slave and a .750 master which gives a 22mm stroke of the slave at full travel.
Full travel of the master is 29mm
