Thanks for the link, that's a good solution for putting the pushbutton in the stock button, but now I'm bummed that I didn't save the abxy button holes, I drilled right through all of it thinking I wouldn't need it
So if I can find an alternate way to make those or make something that accomplishes the task of keeping the buttons from wobbling and falling out, then I'll be good. And I'm assuming the breadboard stuff is pushing against the back side of the controller so it won't move.
!::::::BIG EDIT::::::!
I've thought about it, and since I'm going to spray paint the controller black/yellow in the future, I also thought it would look cool to spray paint the abxy buttons yellow, which would kinda make using the stock buttons useless.
I'll most likely end up buying bigger radioshack pushbuttons and spray paint them to match the controller (plus now I can just superglue them in place in 5 seconds rather than all the extra work to use the stock buttons). Here is what I'm aiming for as of now, maybe in the future I'll make another that uses all the stock parts:
