I think I have an extra set of Sanwa in blue. It should be a blue stick with 6 or 7 buttons that match.
I also have a set of White and Black HAPP comp buttons plus 2 comp sticks (I think, not so sure abotu the sticks). I might be trying to throw them together in a box soon (the HAPP I mean).
If you want blue Sanwa parts I could part with them for less than what you’d import em for. . . however. . . I live in Spokane so I’d probably still have to ship em if you don’t want to wait a few weeks.
