Hi all... I'm a bit late to this party but appreciate all the great findings. I have a Zero case for my overthruster and I got Zero Corp to paint it the right color! 5mm and 3mm Letrasets are on their way to me and I have a panel for the inside all cut and ready for painting. ID - stromo has provided a set of pdfs for my outside stickers. Morganthirteen just completed a run on overthrusters which are beautiful.
I think I am going to use the best guess that stromo came up with for the Kanji, and use a sharpie. There a few sites which translate english to Kanji, and I can fill the gaps with that.
