[Healeys] transmission conversion

[Larry Varley]

Well said Chris, another trap is using a "Heavy Duty" clutch with a BN1 
box, especially if your not Mark Webber. Or better still save what you 
were planning to spend on another gearbox and invest in a new set of 
gears for the BN1 box, which are now available in England ( as a set ).
