[Healeys] Re - Fender screws

[Michael Salter]

Absolutely correct Mike.
The carburetors (made by SU) and everything electrical (made by Lucas)
retained their BSF, BSW and BA thread systems right to the end in 1967 ...
and thereafter in other makes.
The 100 windshield was also something that used BSF and BA threads until
the end of BN2 production.
