As a general rule most items on the 100 chassis are UNF. In the UK we
were changing over to UNF after W.W.II but items such as the engine,
early gearbox, suspension parts etc. that came from Austin mostly stayed
as BSF. In fact the engine in its diesel form kept BSF into the middle
1960s.
You are querying about a BN2. With a very few exceptions your car will
be all UNF except the engine.
To the best of my knowledge there was no thread changes at any time on
the BN2 throughout its build life.
All the best
