Looking for stock bore OEM 5.7 piston

Like the title suggests I'm looking for a stock replacement piston rod combo for my 5.7 engine. I would appreciate if it still has the stock rings as well, but I can probably work around it. It needs to be from the driver's side, as they are actually different between banks. Hoping someone has upgraded and has one laying around they would be willing to part with. Thanks to anyone who can help.
