Where can I purchase piston rings by size.

I am looking for (2) piston rings that measure 1 7/16 expanded diameter (for 1 3/8 bore) by .045 axial thickness by .06 radial thickness. That's about 36.5 x 1.2 x 1.5 mm.

they fit a Yardman ym71ss string trimmer engine. I've tried ebay , Jacks, and amazon and they either sell by part number or only handle certain sizes. Thank you.

papa Hajek the YM70Ss should fit same size bore and stroke. Amazingly enough you may get the piston and ring assembly cheaper than just the rings. Check on here.
