Kohler Parts Looking for discontinued piston ring set

I was wondering if anybody out there could help. me Iam looking for a double set of piston rings for a Kohler
model CV22S–spec 75564. Kohler discontinued them and I’m hoping somebody has A set on their shelf.
Or maybe somebody else ran into this problem and knows of a offbrand set that could be used in their place.
 
Hope you guys can help me thanks     Kurt
