MET Electric loco transfers

Having just become the proud owner of a Harrow Models whitemetal kit for a MET Electric loco (thanks again, jimmysbow), I was wondering where I can get the correct transfers to put on the loco to depict it as running at the end of its career? The ones that come with the kit are not quite the right shape for the later LT livery and there are no smaller numbers for the bodysides. They must be available from someone as I have seen the correct ones on other peoples models. Thanks.
