One new two-piece EPC brand big bore clutch master cylinder and slave cylinder kit (made in Italy), part number 64068319OS/3010224. Sunbeam Tiger 1964 - 1967. This is a 3/4" bore oversize clutch master cylinder - the standard bore is 5/8" bore. This cylinder will increase the clutch arm movement by up to 44%, ultimately providing greater movement of the clutch arm for the same pedal movement. Using a larger bore clutch master cylinder will also increase clutch pedal effort, meaning the clutch pedal will feel stiffer.
If you require a clevis type push rod you can swap from your old cylinder.
