You must undo the dash and the glovebox.
I build my own dash as a DIY and I fixed this:

The kind of fixing is called „tackern“ in German, the factory does it in the same way. Pictures are possible by mail or have a look at Facebook „Morgan News“, some weeks ago.
Here is a picture about the glovebox, TBM has posted it for me.
