The rings are original OEM. I think Cat Man is just wondering how you determined OEM is Nippon (as opposed to some other ring manufacturer (e.g., Sealed Power)). Currently, is seems nobody knows for sure what brand is used as the OEM equipment.

I've built a lot of engines (GM, Ford, Cummins, Mack) and the only company I saw that used their name on rings was Caterpillar.

Ok, one more time, I read here that the piston rings are Nippon’s .
I don’t get to see the rings. I don’t believe they are marked.
I reread the thread and see it was a link from Dr Loch and As linked before, ZZP has the Nippon rings listed.
you can use Perfect Circle, RockAuto has Celvite and sealed power rings.
my engine guy suggests put in the best you can afford. He doesn’t have one brand preference, but different brands work better in different makes of cars.
Hastings has this information

Okay, I think I'm starting to see past the confusion now. Dr Loch referenced ZZP having Nippon rings. But most folks here did not take that to mean Nippon was the OEM supplier for the LNF. Instead, we all just understood the Nippon reference as one possible aftermarket option to replace my OEM rings. So most of us still believe the OEM supplier is unknown, since we've not seen any other definitive information.

The GM engine plant here in St Catharines used Hastings. I can’t find what they use in Tonawanda NY

Just as an FYI...I went to the shop and inspected the OEM rings today. I found no markings on them, as expected. So it's unclear who made them.
Additionally, I observed the "finish" on them to try and determine if they might be cast iron, chrome, or moly. They appeared shiny as if they may be chrome. However, I suspect any type of metal ring would be somewhat shiny after thousands of miles of wear. So I'm not very confident my conclusion is accurate.
Nevertheless, I think I'm going to purchase the Sealed Power rings at RockAuto and I'll lightly hone the cylinders with a 280 grit ball hone to prepare for the new rings. Full speed ahead!

Yes, I'll definitely clean with soapy water and then trans fluid as you suggested. I never thought of using coffee filters. Thanks for that tip!
