I think the majority of those on the rsoc who have fitted them sourced them direct from the USA & bought them via ebay us tbh - only other way to buy them is to wait for the odd time they come up on ebay UK when someone here sells them when they sell their car & parts but a lot of the time they're then much more expensive than just importing from the states

There is a set on ebay UK @ the mo being sold by an RSOC member
