This is the correct cast-iron Dunlop-style cylinder with a 90-degree angle between fluid ports. Until now, it had not been available for decades. Part number C20775 fits all 3.8 E-Type (it replaces part number C17643 used on very early cars) and all but very late Series I 4.2. Those late cars use an identical cylinder but the forked rod is slightly shorter, so you will have to install your old rod on the new cylinder. If you have a late car that has already been converted to the alloy Girling-type cylinder, you cannot use C20775. We hope to have the short push rod available soon, however. How do you know if your car has the late-style cylinder? They can be identified by the short nipple at the front of the cylinder that accepts a clamped piece of rubber hose; all earlier cars had a hard pipe fitted to the front port.
To prevent corrosion, these cylinders are plated gold. They can easily be painted "cast iron gray" for a truly original appearance.
