I'm doing desoldering my MaxKeyboard for switches, there will be enough stab (Costa) for a full size board. I was planning on using them for future projects but if you need them, just wait for me a couple of days (well, lazy problem) till the work done then I'll send you for free
Edit: I'm not sure about the wire of spacebar stab, MaxKeyboard uses 6x spacer so maybe it wont fit on 6.25 but then you could just bend a new one
