Needed: Trim Rings!

i have a set of Blitz BRW-03's (thank you tonioseven ) that were sent to me without trim rings. now as you can guess, they look kind of weird without them, and i was looking to put them on a project that's coming up soon. does anyone have any info about where i can get trim rings for them? i think they're Fujimi (they're female so that's just a guess), and they're 18's. any help/info is greatly appreciated! :sun:
