HEEELLLLPPP!!!!

I have a Hanger 9 Solo Sport trainer (ARF). The servo mounting tray is factory and is made of wood. The previous owner put the wrong screws in the servo mounts and now anything I buy that will fit inside the
servo grommet is too small for the mounting holes. Any suggestions as to how I may mount the servos without trying to rip out the epoxied servo tray?

Thanks a bunch in advance,

Alan
