Um,I don't know. I bought it off of Ebay. Unfortunately,these are the only pieces.
I found some other armor here in the Cargo Hold that I am targeting,but first I'll need to get the money. (soon,hopefully)
Good luck! Hopefully buying different parts from different kits won't hurt you in the end. It's all pretty customizable if you decide to go seamless or not, so I'm sure it will all work out in the end. Are you going for phase I or II?
