I don't have anymore either, like Bill I had bought about 5 extra and sold them all to MTF members. Your best bet I think is ebay, they show up from time to time. Right now there is a seller who claims that he has a Stens 515-510 that will sub as a Lawnboy piston 606607, which is the part number you need, but I could find nothing to back up that claim.
I think you could reuse that piston if you had to, just clean up the scoring, hone the cylinder, install new rings and I think you would be back in business.
