We T type owners and earlier have to deal with:
BA threads and hex heads on dynamo, starter, fuel pump, carbs,
distributor, instruments, ?
Metric threads on engine, transmision, and differential cap
Whitworth/BSF hex on the above metric bolts.
British Standard Fine threads on body components.
Whitworth bolts on the body and some components added to the
SAE nuts and studs for the wheels.
British Standard Pipe on engine plugs and some pipe fittings
BTW: Whitworth and BSF use the same wrenches but the size labels
are different and the threads on the fastener are different!
