#3 sell me that Perfect360*, LOL, just kidding, no seriously sell it to me, no just kidding, no sell it!!!* In all honesty you won’t find any shell that’s built for Japanese parts that’ll fit a Perfect360. Maybe it’ll barely fit in an Hori HRAP 2, 3, or VLX shell, but I haven’t been able kick off any of these projects myself personally.
#4 Some tech talk veterans on this board @hibachifinal & @eczangief have gotten Suzo sticks to fit in HRAP’s and TE’s, and @rygod got an iL Eurostick to fit in a VLX. Not really sure how easy those builds were.
#5 I’m pretty sure the folks at FoeHammer or @souji5 will build you a nice custom case for the right price
