[Healeys] Flywheels One more time

[Alan Seigrist]

Has anyone put the BJ8 pressure plate on a BN1?  I would assume it should be
an easy switch, just keep the BN1 clutch disc and use the BJ8 Pressure
plate.  The clutch lever is mechanical, but adjustable.

Would make the car much nicer to drive....
