⭕ This is a genuine bn2 gearbox it came from a 56 healey 100 left hand drive . I was told it had done 45000 miles . It has its original laycock overdrive fitted.it has LH pedal shaft fitted . But RH ones are available.have not used or stripped this unit .so presume it will need a rebuild .but it is totally complete and casings , and bellhouse are in good condition.if you want your 100 m replica to have an authentic bn2 gearbox this is the one to have as these rarely turn up for sale , most rebuilds end up altering later 100/6 or 3000 side change boxes but they are diferent and not correct for the 100.
