Header panel attachment 36 Tudor!!!

[Royal Ryser]

Can somebody describe how the metal header panel is to be attached om a 36 tudor? I am talking about the formed metal panel above the windshield (on the interior) that covers the radio speaker and windshield wiper motor.

I see that it is attached with screws through the bottom, but are there screws also across the top of the panel (visible), maybe screws and finish washers?

Thanks for the help.
