Hello, I'm new here, but I am in need of replacing the selection keys on my Rockola Empress 1497 model juke box.

I have the replacement keys, and I have the original manual, but can't figure out how to go about doing this. It looks like I need to remove the section above the keys, but I can't seem to locate all of the screws that need to be removed.

Any help with this is greatly appreciated! Thanks!
