silent running

Help! I've hired an engine crane for the weekend ready to fit my rebuilt engine back in the bay tomorrow, but at the last minute I've found a crack on one of the 'ears' of my old clutch release bearing! It can't go in like that, so apart from a Subaru parts desk who probably don't have them on the shelf anyway, is there anywhere in East Anglia that is likely to have one in stock on a Saturday morning?

I can get to Norwich, Ipswich or Bury if needs be... but Lowestoft or Yarmouth would be easier. Or anyone actually got one that they want to sell me if I come and pick up?

PM please...cheers!
