Aftermarket clutch master cylinder options

Some time ago I saw a post about an aftermarket master cylinder that can be adjusted to correct some issues with flywheel resurfacing, besides it looked more like the brake master cylinder (better quality).

I am rid of the master cylinder in my XJ as it always leaks a little (it really isn't old), so I'm considering to upgrade it to a better one. Any info on this kind of products?

Pm Old_Man. I think it's a Howe, or Howell...something like that.

Old_Man, that was exactly the thread I was looking for, thank you so much. How did the master work for you? Was it hard to install?

By the way, is the part number 524-14S? I'm looking at this page and I am just asking because they sell it for braking applications:
