Yes , I have a one on my 3 door its set up like the ryland conversion. My master is a Girling .75 cylinder and the slave is a BMW E30 cylinder.
It dd run a smaller Master cylinder before @ .625 but this did not give it the travel needed so I changed it to the .75 and all works well.
I run an AP Organic clutch plate and cover so not the heaviest unit anyway but I a very worthwhile mod. It makes the pedal about 50% lighter, not quite as light as a modern car but only 15% diff.

Cheers.

Tim.
