I had a link to a UK tool dealer that sold Picador or similar type pulleys, for a reasonable charge they could bore it to your requirements regardless of unusual imperial or metric size.
Now I can't find the link and I've tried a Google search so does anyone know the company I'm looking to find ?
EDIT: just discovered that Bearingboys are one company that offer this service
