440 Pistons, How F*cked am I

Someone on here has to have a spare piston floating around. I have a 440 that's hanging on an engine stand, and I am not planning to use the pistons I take out of it, but I really don't want to tear it apart just to pull one piston out. I have a lot of stock 400 pistons I've saved. I'll dig around and see if I can come up with a 440 piston somewhere.
