3 piece Borg and Beck kit, has a 180mm wide clutch plate,pressure plate and release bearing,fits all cars pre 1990 VERTO assemblies until fitment of 1275cc engines.
From 1990 on the clutch plate was increased to 190mm, for 1275cc which is
GCK152MS .
Clutch kits should be re-balanced to the flywheel assembly as originally done on production. This is because the verto pressure was a heavier item and the main mass rather than the flywheel as on earlier diaphragm models. This was recognised as a small design fault but easily overcome by balancing which is why Rover originally supplied complete balanced Verto assemblies as repacement parts.
Do not forget to the change the
AAU2866 seal for the clutch release bearing.
