Genuine style Cooper “S” close ratio laygear manufactured in the U.K. to suit 4spd all syncro Morris Mini Cooper “S” and Leyland Clubman 1275GT gearboxes.
In all 4-synchro remote gearboxes, the internal gearsets were largely identical except for the laygear and 1st motion shaft, which determined whether the gearbox was standard or close ratio.
