Hello all,

I'm in the process of adding sound deadener to the M28 cabinet that I'm restoring and I was wondering what accessory or mod goes above the "SIGNAL" / "POWER" stamps in the attached photos.  Cabinet is a LAAC 236 GA.

I'd like to keep the holes accessible to my future self or future owner if they wish to install the part that goes there.

Thanks in advance,

Nicholas Gromak
