THE DUKE'S PISTON FITS HUSQVARNA 350 351 353 45MM

So I've been searching for a piston that would fit in the open port husky 55 with the 45mm cylinder. Those cylinders make this just usable in the 3-cube racing class! I assume this would work in the 50/51 chassis as well. Minn is highly modified! I'm not sure if this will fit without machining as my cylinder was already machined by me before purchasing this cylinder. So may not work on a fully stock saw. I would love to throw one in a stock one to verify, but this piston was exactly what I had hoped for. My racer is screaming!
This is with a 045 thousands pop-up cut into the piston, the combustion chamber has been cut and the base has been lowered about 060 thousands.
