1.1 Thermostat flange

New to mark 1s and my first part failure seems to have turned out to be an obsolete part

Im looking for a thermostat flange as the one I have knackered

 

Part number is 052 121 121d

I will pay for postage

thanks

Cathal

update.. have found a supplier in Holland that has them. If anyone need one, I  can pass on the details
