Boss Pedal top plate spare

I’m looking for for a replacement top plate of the Boss Overdrive Turbo (OD-2)
The part that you step on to engage the effect. Not the electronic plastic switch component. The metal top piece that is hinged via two little screws to the metal chassis.
Any ideas where I can get one?
Aesthetically I would prefer the OD2 top plate, but any generic livery one will do.
