Hemi Piston Part # ???

[OldRunner]

Looking to see if anyone can tell what size this piston is, part # is 3571046, says 005 on the top ??? I am looking for a Std size piston for a 426 Hemi, I have found these but need to know if they are Std Bore. Thanks

The P3571046 piston has the following specs:

Pin Dia: 1.03"
Piston O.S.: 0.005"
Piston Position: Right
Compression Ratio: 12.5:1 High Top

The Left side piston part number would be P3571047. These were Direct Connection/Mopar Performance pistons.
