The MK1/MK2 Mini not only has a smaller rear side quarter window than the MK3 but also the rubber seal is cosmetically different. The only seal available for years was the MK3 which has a grain texture on the inside edge. Now in stock are very good reproductions of the original MK1/MK2 shape seals. Cut to same length as larger mk3 windows for alternative uses, priced individually. These also fit mk2 cars.
