[Healeys] Motor Mout Bolts

[John Harper]

Curtis

There is another way of how one can get a close idea of what threads are
used. All the body parts that were new in the 100 are UNF. However parts
that were from Austin vehicles such as the engine, BN1 gearbox and early
rear axle stayed at BSF.

'our' 100 engine went with only minor changes to become the 2.2 litre and
2.5 litre petrol engines that continued well into the 1960s. These
continued BSF until phased out

Best regards
