I'm adapting a TR6 trans to my GT6. It belatedly occurred to me that  
the proportions between the slave and master cylinders may be  
different from a GT6 to a TR, and I won't end up with enough throw-out  
bearing travel if I use the GT6 bits.  What is the diameter of the  
master cylinder piston and the slave on a TR4 or TR6?  The GT6 is 5/8"  
master and 1" slave.

Thanks!
