idler pulley

[rich]

hi
does anybody know what idler/tensioner pulley to use for a 2.0 zetec black top?

Been trying to search for a suitable tensioner/pulley to fix to the engine so that the water pump spins the correct way. no luck.
had a Audi turbo one lying around and made that fit for now but it only has a 4 groove pulley.
as you can see in the rubbish picture
