Order the gasket, with the regular Royal Mail, they told me I'll get a tracking number and track the package.Unfortunatlly the tracking number does't work on the web Royal Mail. So just waiting, don't know how long, until it will arrive!!!!
They last much longer than the original black group gasket.
