I also have the McLeod set-up, and Tony is right. You need to measure the distance fron the clutch fingers to the base of the Tranny, than find out how much volume your master pumps. It was tricky to establish the correct spacing on this set-up. Now that I gave given you no information to your question, here is the web site.
