Hello Nacho, If I had one I'd let you have it for free (except for the ride!). you might put an ad in Craigslist in many locations worldwide, there's gotta be one floating around out there somewhere. I didn't go back & read the whole original thread but is cutting notches in another piston a potential fix or maybe just spring for a single custom machined piston (it'd be $$$ but it would give you closure). EDIT you could specify the wieght to match the others & you could hone that specific cyl (if needed) to match the piston to wall clearance of this particular piston type (as needed)
