The adaptor flange has 6x70 hole circle so you can fit standard racing wheels with custom button plate to it.
The adaptor plate is to mount the Fanatec CSL wheel to the adaptor flange. Only using custom paddle shifters.
For the paddle shifter I used these ones:
Neue Version Paddleshifter Only ! from

If you use different shifters, you can use the Fusion360 file to change the mounting holes.
You have to solder your paddle shifter wires to the swithes on the original PCB.
Use M5 screws to mount the adaptor plate to the flange.
