Anyone know where I can get cover gaskets for my 5JJ online?

I've got very good service from Bike Bandit in the states. Online diagrams so you get the exact bit you want and the exchange rate at the moment makes purchases cheap!! They only send international via Fedex but even including that I only paid £30 for my crank pulley whereas the cheapest I found in the UK was £45 + delivery + VAT.
