Okay, so I've got a vivanco. Compact board with XM's. You can look it up with that plus geekhack on google.
It has a plastic plate.
I've desoldered all the switches in it. I've also desoldered all the switches out of a AEKII.
The AEKII has a metal plate. How hard would it be to somehow modify the AEKII plate to match the plastic one before I put in the new switches?
