Here is a complete Shift Boot Kit for your MGB or MGC built after 1967 (all-synchro transmission models). It comprises a new rubber boot, new vinyl boot or gaiter, and a new factory retaining ring.
Some MGBs came with a chrome retaining ring; we will be happy to substitue one of those at no extra charge if you prefer.
Note that MGBs built before 1973 were equipped with only the rubber boot, and no vinyl gaiter. The vinyl gaiter is a nice upgrade, but if you just want the rubber boot, we sell those as well. Please contact us for details.
