Clutch all now operational not without a few problems on the way first is the new master cylinder is 3/16th pipe and fitting the new slave is still 1/4in but with a UNF fitting so I made a little fitting one end 3/16th one end 1/4in then silver soldered the respective pipes into the fitting new swaged ends and hey presto a complete system ,master all fitted fine used the old clevis with a new pin surprising the wear on the old one, the new master is not integral with the reservoir so a remote reservoir has been fitted on the passengers side and piped across and into the inner wing all looks neat and tidy the action now that I have the correct hydraulic advantage is very smooth and surprisingly light so the rest of the engine is back together run it up tomorrow and set up the water injection.
