The early MGB had steel/tin caps on the Lockheed brake and clutch master cylinders. Later MGBs utilized a white “nylon” plastic cap. These later caps will fit the earlier cylinders. It is also not uncommon to find caps from solvent cans used, as they were very close in fit and appearance, without the slot across the top of the cap. These caps were also used on the MGA and probably other Lockheed cylinders of the same time. Apparently a company specializing in MGA parts is undergoing the remanufacture of these caps, but at writing these are not available.
