07 sonata Which Piston to order?
 

I have an 2007 sonata with a 3.3. Water got sucked into engine and bent a connecting rod, and the crank scratched the piston. Hyundia lists 3 different pistons- std a, std b, and std c and 5 different rod bearings a, b, c, d, and e all std. A Hyudnai tec told me theres a series of letters behind the crank pulley that indicates which piston for which cylinder. I pulled the crank pulley and there are no letters behind the pulley. Today im going to pull the piston out and see if theres any numbers or letters on it. Any help would be much appreciated.
