I have bought a replica here in South Africa, but noticed that the brake master cylinder only has one outlet. I know in the UK it is a legal requirment to have a dual system, but in SA it isn't. Is it worth the hassle of changing to a dual set up? I understand the safety issue of having a single oulet, any other concerns i should note?

The donor car was a triumph sptifire, so solid front discs and rear drums.

i don't think there's any other concerns, but the risk of having all your brakes fail is enough of a concern for me

i'd definitely change it
