34 3 Window rumble hinges
 

I just pulled this 3 Window out of the barn, stored there since 1958. It originally had a trunk but now has a rumble seat lid with hinges attached to the lid. I don't think there are any brackets or whatever attached to the body. What else do I need? Where can I get the parts? I see that several places have the parts for the 5 Window but specify that they are not for the 3 Window.
