I'd second that, could be fixed up to look decent while still original. Of possibly swap for a pair of different seats, would not even have to match design or colour.I'd think the chances of finding any in that colour pretty remote without any damage....
Think you'd be far better looking for a local trimming company and have yours repaired.
You'd be amazed what's repairable, and often cheaper than you think.
Hope you get sorted ok...
