MODIFYING SBE Console 6 for channels - best method ?

Hello, I'm checking around on channel mods for the SBE Console 6 deluxe base station ! I am wondering also about that mod where the channel readout shows channels up to 99 on this radio I've heard about ?

So what is some good methods for modding the SBE Console 6 for channels above 40 ? I need documents ! Pictures and knowledge on better ways to add extra channels for the SBE Console VI (6) please !

I assume clarifier opening is easy enough though if I need that done...

Thanks...
