Order a ring from one of the respectable online dealers, call if you need to talk with them to make sure you’re getting the correct ring.

Usually one can get a ring .1 mm larger ring than the piston, so if for example your piston was oversized 0.5 to 52.50 mm, then you’d get a 52.60 mm ring and file equally from the ring ends until it fits to the gap spec ( .1 mm equals almost .004 of an inch).
