Description
This is a TRW brand clutch master cylinder for a Triumph TR6 1970 to 1976 with the 0.70" bore size. TRW has changed the mold on their cylinders so the units no longer carry the Girling cast into the side of the cylinder. Also the metal cap has been replaced with a plastic cap, but the metal caps are able to screw onto the cylinder. Cross Ref.# 581-541, 64066117, PMC133, 581-540
