sbt piston rings

[cameron da river rat]

i am looking for a set of kawi 550 piston port, 1.0mm "thick" style rings that kawi used from 82-85. will the sbt 1.0mm rings fit a stock oem piston in a 1.0mm over size? there were two different types used on the piston port 550, thick style and thin style, im looking for the thin style but your catalog does not specify piston port or reed engines, thick or thin style piston rings.

thanks.....
