B-17 spar and landing gear attach?

I think my ambition will exceed my ability,but I’d like to try a cutaway B-17 in 1/48. I currently have tons of research material (manuals, books, etc) but can’t find any photos or drawings of the two spars and main gear attachments for the B-17… especially the inboard sections (fuselage to outboard of the nacelles.) Anybody got a picture, drawing, or source they can provide? Sure would appreciate it.

My best regards

Search for the MEMPHIS BELLE on Google. They’ve got the wings off her right now
for a full restoration. Lots of photos of it so some might be helpful to you.
