vitara piston/ring question.
 

hey i have some vitara pistons 75.00 mil and i have some npr rings.
my question is will any npr rings fit.
i got the pistons/rings from some guy on nwsr before i knew anything really and i know they go together but im not sure if these rings are right now due to my machine shop saying they weren't. i lost the ring box after setting the rings on the piston and don't want to buy new ones.
but i will if i have to :1
