Hardware Replacing the 3DS Shoulder buttons, need help.

[MTSoph14]

I have been trying to fix my 3DS's R button for some time now, but after opening in up (no worries, warranty expired) I found that the R button's cable was barely attached to the system. I put it back in properly and sealed the system shut. Now the button works...75% of the time...sorta. When it does work, it sometimes thinks I am mashing it repeatedly, and when I am tapping it repeatedly it doesn't register. I would like to buy a new cable and black button structure to repair it once and for all. Does anybody know where I can buy these items? I need help pretty badly.

No idea if this is viable, but you can look for a broken 3DS online somewhere for cheap (with the buttons still in good condition, of course), and just cannibalize the pieces you need off that.
