You will need to replace the whole thing: piston sleeve and rod. The last time i checked Amain has a few parts left

pistons and sleeves are matched at the factory. they need to be replaced together and broken in together.

Keep the rod. USe it during the break in of the new piston/sleeve and then replace. Once the engine gets tired. Replace the bearings and send the piston and sleeve out to a place like OS Rocket and use that rod again for the breakin again.

grp piston and sleeve are few and far between. out of stock everywhere. im talking everywhere. im gonna try to grab a junk grp and try just the piston...its down to either that or trash it. another new engine wasnt in the plans..
