Mark II (1967-1969):

These cars were launched at the same time as the MGC. The major evolution in the MkII cars (the official nomenclature was the fourth series) was the introduction of a new fully synchronized gearbox with revised ratios. An automatic gearbox also became an option (until 1973) at the time. The electrical system’s polarity was reversed to negative earth, whilst American cars received a (horrible) revised dashboard known as the Abingdon pillow, a third windscreen wiper and the first of a series of engine changes due to emission control equipment (the last American spec MGBs had as little as 62.5 BHP.). The launch of the MkII series also coincided with the appearance of the MGC.
