I have a brand new set of Sealed Power E-642K 40 piston rings that is missing rings for 2 pistons. These are for a 3.950 bore. I had to buy this set to replace the rings on two pistons, and don't have a use for the rest.
I'm just trying to put some feelers out there to see if there's any interest - I'd rather not throw them away. Shoot me an offer, I ship USPS flat rate so it'll be about $8 for the ride. Located in Sahuarita, AZ. Thanks for looking.
