whats your mechanical knowledge is the key question here.
What prior experiences have you had with mechanics, on a 1 (easy) - 10 (difficult) job I rate the clutch master a 6. Unless your small and non claustrophobic it will be a 6, you will be working in small dark places that require a good light and you will be dealing with a few small parts that go together just right. Its not hard, but it can be time consuming and a pain.
I've seen so many people working on cars that were making ridiculous mistakes that I feel some people just shouldn't be working on cars. I still remember a guy on the side of the road trying to repair a blown head gasket with a adjustable wrench , pliers, and a screw driver. He couldn't even figure out how to remove the valve cover.
