i dont want to sound like a right mongo

but i've got a alt drop bracket to fit to an escort after fitting a big turbo,
i've got the bracket but cant for the life of me figure out how to fit it, i cant get anything to line up, either on the alt bracket or the block,

is there differant brackets for differant types or am i missing something
any advice or pics please would be great as i'm stumped
sorry forgot to say its running the twin v belt set up from a saphy not usual escort ribbed belt
