408 Interior mirror mounting

[Sterly]

The 408 I'm working on has a new headlining but hardly any holes for fittings. I've sorted out the dome light but I have no idea on how the rear view mirror is mounted. From what I've seen in an internet search there's a console with what looks like a speaker and possibly the mirror screws to that? Does anybody have any pictures of what the assembly should look like and exactly where the mirror screws into? I can't find any console among the parts unfortunately.
Thanks for any help
