For the R65, I'm using a wilwood 0.7 master cylinder from Rally Design, a remote reservoir and drop pipe also from Rally Design.
For the Slave cylinder I'm using a MGF Slave cylinder.
For the mount I've got a custom mount being made by Talon Sportscars.
Can highly recommend Dudley at Talon Sportscars hes very very reasonable for cost and has been on the kitcar scene for ages and knows what hes doing. He is the official build agent for Hawk Sportscars. Am sure he could work something out for you if you want. His contact details are:
