When I had my 159 I remember ordering one from somewhere on eBay for around £8. Seemed steep even for a 'bespoke' bit o rubber but it saved hassle and was annoying me. Subsequently realised it may have been sucked up by Hoover so be careful as they aren't glued down!

I'll see if I can find the seller in my account history and will post back if successful.

Just checked but it appears the seller (hwmalfaromeoparts) on ebay doesn't have any at the moment but has a limited stock of other Alfa parts. It was £6.95 + p&p for the record.
