Toilet seats with distance between hinges of 270mm

[RajendraH]

Hi

Looking for a toilet seat (D shaped) with the distance between hinges of 270mm. Width of seat is about 410mm and length 440mm

Any suggestions would be welcome. The toilet unit is Ideal Standard and is over 20 years old. It is is great condition, but the toilet lid is broken as a builder stood on it whilst painting!

Thanks
