Niles,
I'm also using the Wilwood pull type slave cylinder. The spec on this thing is .750 dia cylinder & movement is just a tad over one inch. I use a .750 master cylinder. Got the whole thing from Summit.
Frankym's suggestion of using hemi joints on both ends is a good idea. These cylinders have been known to develope leaks if it has to pull on an angle. When your fabricating your linkage, keep this in mind and try to have the thing pull in a straight line. And as you've read above, make up a good sturdy bracket
