Mk1 Wheel Centre Discs

Does anyone know where I can get some Mk1 Wheel Centre Discs like this?  They are 45 mm in dia, bevelled.  Ideally with the collars to go into the hubs.  Thanks, John.

Have you tried EBay?

Yes, I have a Search on ebay which has been running a month now; there are currently 543 discs on ebay, but none of them like this. My local dealer tried ordering from Mazda, they quoted £30 a disc; when they arrive they were wrong! They were raised like a Mazda 323. But thank you for replying.
