The fact that Total Seal has rings on the shelf is amazing. Price is relative to rarity, so the fact they have them makes them a bargain. Wiseco is usually really good about custom making rings for one off things. Might be worth another try. BTW, don't waste your time and money on "OEM" NOS crapola from Asia. I've spent 12 years behind a Kawasaki parts counter and run into all kinds of horror shows from that s**t.
