As John has explained, you cannot change the 2nd stage rings without removing the whole piston/rod combo (at least not easily). That's why I said to replace all the seals, the cylinder gasket is paper and not really reusable if you believe in doing things correctly.
Did you get it rebuilt?

Adam,I hope my method works! I'm sure there are proper tools for stretching and sliding the seals over the piston, my shade tree approach worked for me Mind posting up a link to the seals you ordered? I'm sure others would find the info valuable as finding things on AliExpress can be challenging to say the least....John

Sometimes they will combine the shipping if you message them and ask.
