Yes, I did. I paired one with a 6918-07 RXT clutch and the clutch failed shortly after break-in. Quite a nightmare story that's documented here. Several different highly regarded people in the industry told me that the McLeod slave cylinder is junk and they all recommend the factory part.
I bought one of McLeod's adjustable throw out bearings, but having heard a similar thing told to me, I used a Ford replacement, so I don't have any direct experience with one. I do have an RXT, however.
