Need some help with a piston

I started to put this under the "cylinder bores" thread, but opted for a new one.
I picked up a set of 11 fin cylinders last Summer, and one of the pistons got bent in shipping.
I'm hoping someone out there on the web board can help out.
I need a replacement .070" 3.422 piston. These cylinders have been bored to .070 over 3.422, and been run at some point.
The bores are in fine shape, the pistons fit well, but the one's skirt got bent pretty badly by a cylinder when they were shipped to me. I don't want to go with aftermarket pistons, 'cause they are all sized to the 3 7/16" bore.
So, does anyone out there have one 3.422, .070 over piston I can use to salvage this set of jugs?
Thanks for any and all help,
