B18 B20 flywheel
Late type B18/20 flywheel. This has the correct centre to clear all the modern clutch kits available.
If you have the older flywheel without the step just before the centre recess then you will need to either machine your flywheel the same as this type or replace with one of these later flywheels.
Fits all B18 and B20-1973 (all with 6 bolt crank) manual engines
