Default Need Help; LQ9 piston identification

I have an LQ9 6.0 LS with a damaged piston. I don't have any specific info except it the engine was taken from a GM truck 2004 or later.
I don't have a VIN. Hoping someone in this forum can help me find a part number or an actual piston.
This is the piston I am trying to find a duplicate for.

That’s a Delco piston. I tried finding one at Summit but they are discontinued. You might end up buying a complete set of replacements to cover this, for balancing reasons. There’s a lot of GM pistons with different part numbers that will work for that engine…Silvolite makes an economy set also. EngineTech is another economy brand that’s not bad. I’ve used EngineTech in a couple builds for guys with good results. Whatever you buy, make sure it comes with pins and rings. Read the fine print.
