Installing the Rumble Seat Lid

[Elcastor]

I am trying to install the rumble seat lid on a 1930 Standard Roadster. I did not take this apart so I do not know where these pieces go, or how they are put together. I am assuming that the square nut is the correct nut to go on the hinge bolt. I do not know where the square washers go in relation to the hinge assembly. Where do the 2 larger pieces go? Any help would be appreciated. Thank you!
