Need help on 32 bed

[Hotrodswe]

Hi all
I've got parts for my 1932 pickup bed, but some are missing so I wonder if anyone could be kind and upload some photos showing the underside of the bed so I could understand how the cross members looks like and others.
I've only got the sides and front lid and rear lid, so any photos/explanation of the rest of it is really helpful

Thanks
Ulf
