Alternator needed urgent

[Yorkie]

Right turns out my alternator is ... broken faulty something like that. Anyway I need a new alternator quite urgently, they all seem to be very different. Where I can I find the right one for a mk 2 1.2 nova?

If new try your local motor factor and ask what options they have available then get your one removed to check it when you go there if it's broken you may as well have it to compare it to the new one
