Yeah but his website now says they are not cut. Which sucks because you don't want to make that joystick hole yourself....
About the installation:
- remove old CPO , sand and paint panel
- put CPO on, temporarily install the P1 and P2 button making sur the CPO is nicely aligned
- lift left side of CPO, remove protection on the back and cut it in half with scissors (the protection, not the CPO

)
- roll back the CPO sticking the left side to the panel
- remove buttons, lift right side, remove remaining protection, stick right side to CP
- done, perfect installation.
