Thanks for your imput. What I have is a 235 chevy and a 52 Chevy truck bell housing with a small clutch and diaphram type pressure plate. I am not sure of the travel needed for the slave. The motor is out of the car and I was not able to check it. What I think I am goint to try is this. I have a 3/4 slave from a Datsun 280Z. This slave used a 5/8 master cyl. in the Z. These master cyl. are cheap at the parts store. I will try this set up and see if works ok.
