Maybe. I have some thin rings that are about 57mm
Pm a price.
Wait a minute. We need to establish if these are what you need. I am not going to take these back. There are about five sets. They are just loose and not marked. They may be used or new, or some of each. There are at least two different thicknesses of rings. Let's narrow this down to something besides price. What do your old ones measure? Why are you replacing them? What is the size of the groove in your piston? How is the bore in your p-60?
I am not a supply house and can not guarantee what these are exactly for your saw.. I have built many many saws and got these from a man that also built many saws. He is gone now so I can not ask what was the exact application. If I would use these I would first see about the thickness and then about the size of the end gap after I squared them in the bore. I can't do that for you as I have no p-60 cylinder. I know you are anxious to get this saw together but let's take some time to get this right.

Rings are worn out. Its only pushing 90 psi. The pistons and cylinder are clean otherwise. But i will have to take it apart and measure the thickness of the rings first.

https://www.arboristsite.com/community/threads/pioneer-p60-low-compression.196851/When I was big into building thin 2100 Huskys, I would only replace the rings when they were a certain distance back to front and the end gap was excessive. Most of this thin ring stuff is voodo to a lot of guys. Loggers loved the thin ring pistons and would just replace the rings once a year. The low drag (tension) made more power and was easy on the cylinder walls. 90 pounds on the string can become a lot of compression at 10K
