1930 Coupe Exploded Diagram

[53OlderThanMe]

Hi,

I'm considering a purchase of a coupe body that is in pieces and pretty rough metal wise. I am looking for a diagram of sorts to help me identify body parts so I know what is missing or what to look for as a replacement patch panel. The body is all apart with no wood so a bit of a puzzle for a rookie like me. In particular the roof area inner edges I guess I would call it. Looks like they are fairly complex and had some tacks or small nails thru the metal to hold on a roof panel. Are patch panels available to cut those out and replace?

Thanks for any help
