I am using the later stand-alone clutch master as comes stock on my car
and the supplied slave. I don't like it. The pedal action is too
short/quick and a little stiffer than stock. Care is required to take off
smoothly, but I got used to it. I asked Bill Perry about it and he

I readjusted, but my clutch was already adjusted as tight as I felt
comfortable with. I told Bill that I had heared of someone adapting the
stock slave and he responded:

I think a lot of people would be thankful if someone would do the research
to find a bigger slave cyclinder that fits. I would be one of them.
