Wilf,
The filter I bought is THE most common size for the housing we both have.. It is stock height, I had it in my possession, and so it is not a custom make, but standard K & N production. Here is their website, I bet they can sell direct, or they can give you a retailer in the UK or EU that can sell to you direct.

Hope you find one, they are all I would use on a motorcycle or high performance motor of any kind.
